As I thought, you're a good person. From the bottom of my heart, I think she is Miss Tsun-pure who is prim yet pure. Somehow, I can't help but think she's very cute.
Kimito Kagurazaka to Aika Tenkubashi, from Ore ga Ojou-sama Gakkou ni "Syomin Sample" Toshite Gets-Sareta Ken

"Tsun-pure" (JP) is a term for a tsundere character who is very innocent-natured, naive, and excessively pure, even if they aren't always honest with themselves about their true feelings. They have such a pure personality that they easily believe any and all lies told to them causing them to be rather naive. Because of their pure nature they are incapable of lying and are therefore honest to a fault so they will have to resort to covering their mouth with both hands to prevent themself from honestly confessing their true feelings. They are shy and weak-willed so they have a tendency to runaway when faced with even the slightest difficulty in their relationship. After getting closer to their love interest they will start to make an effort to start being deredere with their love interest, such as shyly giving them gifts for Valentine's Day or cutely blushing when their love interest calls them cute.

They are a mix of a “tsun” personality with sincere, untainted purity.

Etymology

Meaning of the Term

Tsun-pure (ツンピュア) is a combination of "tsundere" (ツンデレ), meaning "a character who acts harsh towards their love interest to hide their feelings of being lovestruck", and "pyua" (ピュア), meaning "pure (purity, sincerity, naive, and innocence)".[4]

Origin

Ore ga Ojou-sama Gakkou ni "Syomin Sample" Toshite Gets-Sareta Ken

The term originates from the 2012 harem romance manga series Shomin Sample (JP) to describe the character Aika Tenkubashi.[4]

Aika was raised as an ojou-sama so she is rather naive about the world. She also has no friends and often has to eat lunch by herself in the bathroom, so she is desperate to make friends and forms the Commoner's Club where she meets her love interest Kimito Kagurazaka. Aika is so pure and innocent that she easily believe all lies told to her, something Kimito often uses to tease her. For example, when Kimito gave Aika a superhero book commoner's read she was convinced that all commoner's are superhuman and asks Kimoto to teach her how to do it too. Kimito then makes her do an embarrassing pose and catchphrase to activate her powers. When she starts to question that nothing happened, Kimito tells her she has a huge aura and can control time. When Aika uses her power to "freeze time", Kimoto holds still to play along. After this Aika takes the opportunity to get away with things such as calling him an idiot while flashing him or drawing on his forehead. However, as she gets close to his face to start drawing she begins blushing and instead takes the opportunity to kiss him instead because she couldn't hide her feelings in the moment. When Kimoto accidentally blinks and exposes his lie she becomes annoyed with him and goes off.

She is so pure that she's physically incapable of telling lies. When Kimito asks her straight up "Do you love me?" she immediately puts both of her hands over her mouth to stop herself from talking, and preventing herself from speaking took everything out of her. When Kimito asks her again she once again puts her hands over her mouth, though Kimito believes she's attempting to stop herself from insulting him. When he asks her instead if she likes raisins she starts to answer, before quickly switching back over to liking him. This distracts Aika long enough that she answers honestly and says "I... I love you." Another prominent moment occurs when Aika is giving Kimito mouth-to-mouth and the other girls walk in on a scene where it looks like she's kissing him and after panicking, desperately trying to come up with an excuse, and then thinking it over she said "Kimoto's lips are soft and they feel so good!!", showing her inability not to say exactly what's on her mind.

This excessively pure nature combined with her "tsun" attitude causes Kimito to label her "tsun-pure", a girl who is prim yet pure. Aika was first referred to as "Miss Tsun-pure" in chapter 9 released in March 2013.[3][5] She was also more notably referred to as that nickname in the seventh episode of the 2015 anime adaptation titled "The Tsun-Pure in Her Element" (JP).[1][6] This term is not present in the original light novel version as it was coined specifically within the manga adaptation.

Localization

The term is officially romanized in English as "tsun-pure".[2]

This girl, she'll believe you so easily. She's pure, or rather too pure...
Kimito Kagurazaka about Aika Tenkubashi, from Ore ga Ojou-sama Gakkou ni "Syomin Sample" Toshite Gets-Sareta Ken

They are incredibly pure people, or rather they're way too pure. They are way too pure to believe someone would be capable of telling lies so they'll believe anything that is told them. If their love interest tells them that all commoners are superhuman, they'll believe their love interest and ask to be made a superhuman too. Even if their love interest makes them do all kinds of bizarre movements and saying to "get their super powers" they'll do it with full enthusiasm.

(Ah... Ah... I've got to say something. Something... Anything... My Situation...) K-Kimoto's lips are soft and they feel so good!

They are overly honest around others, but quite dishonest with themselves. Because of their pure nature they are incapable of telling lies so they only end up expressing their true feelings when they go off.[7]

Unlike a standard tsundere character who will say things like "it's not like I like you", a tsun-pure character is so pure that they are incapable of telling lies. If their love interest ever asks them "Do you like me?" they will have to quickly cover their mouth with both hands to prevent themself from speaking because they know if they do say anything it's going to be their true honest feelings.[8]

If they start getting jealous and following their love interest around, if their love interest asks them what they're doing they'll honestly start telling them they got jealous and wanted to get close, but as soon as they realize what they're doing they'll try to shut their mouth, though by then it's much too late.

At the same time though, they are often dishonest with themself. If their love interest calls them a good person they might feel like they're not, that they're just doing things to be a "popular girl" and are actually very selfish. However, their love interest can see this is actually a lie and they can see just how kind and selfless they actually are.[3]

*shyly* I... I like you.

Despite their seemingly arrogant nature, they are good kind-hearted people who always do their best to make others happy, even if they're not fully aware of it themself.[3] They are also very pure and innocent when it comes to love and romance. Because of their pure demeanor this is often the first time they've ever experienced love, so they are very naive when it comes to romantic things.

Despite this they will start to be more honest with themselves and be able to confess their feelings to their love interest. They may do things like working up the courage to give their love interest a gift on Valentine's Day or asking them how they look so they can hear their love interest call them cute.

Differences From Other Archetypes

This type is most similar to ojoudere since the innocent and naive behavior is commonly found in ojou-sama characters. The main difference is simply that ojoudere characters are more on the spoiled side of wanting to constantly be cared for by their love interest, while tsun-pure is more dishonest and arrogant in nature. Additionally, just because ojoudere characters are naive doesn't necessarily mean they are pure and innocent like a tsun-pure character, however, there are many characters who could fall under both types.

It is also very closely related to the tsunbaka subtype, since bakadere characters are also innocent by nature and tend to not always see through lies told to them. The main difference is simply that tsun-pure characters don't have to be forgetful or airheared so most tsun-pure characters wouldn't fall under tsunbaka. With regards to the opposite, it is very common for tsunbaka characters to also be pure and innocent enough to be also classified as tsun-pure, though this is not necessarily always the case.

She speaks like a commoner and has such a pure personality that she easily believes lies, which is why Kagurazaka Kimito calls her "Tsun-Pure", a combination of the words "tsundere" and "pure". On one hand, she is very selfish and self-centered, and has a tendency to act self-righteously without regard for the inconvenience or hardships of others. On the other hand, she is shy and weak-willed, so she quickly runs away when faced with even the slightest difficulty, often irritating Kimito. Since she has no friends, she forms the Commoners' Club with Kimito in order to stand out.”
