Smile
Alice Chance was a well-known girl, lots of people got annoyed, lots people also admired. She didn't give shit.
So let's get to the plot.
She is single, joyful, lots of guys are attracted by her attitude. She didn't beleive this due to her said "ugliness" even though she was not that ugly nor that beautiful.
You could say she's practically average, but I wouldn't call a person like her average.
She's the one to give advices.
One day when a blue envelope starts popping up from her locker a week before their heart festival. She got curious and she herself needed advice.
She also finds out that the guy of her dreams, her female nerd-bestfriend, her gamer friend and other characters are asking her for advices, even though she herselv is confused.
I'm not gonna tell you who the other main characters partner or enemy is, because that'll ruin the whole point of you guessing who it is.
And it'll only depend if you'll read it or not.
"Please, smile for me everyday"
