The whole story is so wholesome and sweet. One of the best romance I ever look over. Story is not dark or annoying with waste of time moments. It is jumping straight to the point. There no have too much scenes in school, directly going to date to next date, I love this kind of present of story and events. The main heroine have a blind concept of relationship, she give everything to every boyfriend she ever had. Runa want to have romance relationship like her parents, they was started to dating in middle school until she become 14yo(around there) but they got divorce. She lovethe idea to have such romancing relationship like her parents. Probably the parents did not explain to her what is actually a relationship.
The main hero in the story is a boy which is a person which character of available to listing his friends and take care, also search for advice of his friends which mean he kinda respect them. Because he respect and want to be honest, he did not break and he did his promise, when he could say no. The promise is to confesses to the girl he likes.
Runa's past boyfriends was people which idea to manipulate her, to use her, only because she is beautiful. She has never a person like him, Ryuuto is never had a girlfriend, he is shy also he care. Runa no matter how bad the past boyfriends was treat her, she never play bad with Ryuuto, she trying hard to make him happy, but Ryutoo show her is not need to do something if she dont want, she realize what is real relationship, what is to be with someone and do what ever you want and you can feel your are in safezone.
Runa and Ryuuto learn to grow by mutually sharing experience and character.
p.s. Imagine if Runa was a male, what success rate would have if want to have a relationship in school with this mindset.
That story is sweet candy for me, I love to see few more chapters.
