From Evil Flowers:

Momoe is the type who accepts everyone’s opinions without contesting them regardless if they are right or not. That’s why people around her tend to call her dumb or stupid. Never showing a hurt face she’ll always smile back at them and she won’t even get angry. Takasugi, the school’s idol, gets to know her after some meetings in the infirmary and he’s amazed by her lack of self esteem combined with a warm smile ready to be given to anyone. She also starts to feel attracted to him, but is love what Takasugi feels or only curiosity?
