hayamine isnt the 'worst girl', but she's certainly the worst option for hirose. hayamine literally just wants to get her life figured out with a job before engaging in romance, theres nothing wrong with being a little more mature than the average HS student. also hirose is such a fucking idiot, if those two did date now, hirose would totally do something dumb like forget a condom and end up impregnating the girl.
now while theres nothing wrong with what hayamine is doing, she still shouldnt be his preferred girl. shes the mature one thats definitely going to make more money than him in the future, take care of the finances and will call him an idiot repeatedly, while he just takes it. they dont have an equal level of respect for each other.
meanwhile prez is smarter than hayamine and still treats hirose equally, is very attractive, and has a lewd and innocent side to her. she's definitely the best option for hirose but hirose is a dumbass like i said.
as a side note, i hate how hypocritical hirose gets for hayamine just liking and looking at akai for a justifiable reason, meanwhile he's doing WAY more with the other two girls, and thinking nothing of it.
