sensei vs. mamura

WARNING : I am pretty sure there will be spoilers so you have been warned 

I've noticed that people don't like relationships between the student and the teacher I always wonder why? DON'T compare real life with anime/manga . It's just who's going to fall in love in an old geezer who looks as old as your father ? I don't think someone would write a manga about a student in love with an old dude , instead the difference would be a few years (7-12 years) It's not that much . So about 2 months ago I've noticed people posting pictures of a manga called "hirunaka no ryuusei" online so I asked my friends about it and they said it was really good, then I started reading it. Ever since I started reading the manga I wanted suzume to end up with shishio because A LOT of things happened between them which it made their relationship become AMAZING , but then when she asked him if he loved her, he said no IS HE AN IDIOT? I think he is ,but then when I think about it she actually believed him then they're both IDIOTS . Also most readers prefer Mamura. it's not like I don't like him or not but I prefer shishio . I know that Mamura supports and treats her how she's supposed to be treated, but that's my opinion . If she ends up with anyone or no one that's her decision and if she's happy then that's all she needs thanks for reading ◕‿◕
