Based largely on the anime and told from Karasuno's perspective, the main story's romantic relationships are rather casual, and there will be individual side stories later. To avoid any plot holes, there will be no scenes in the main story where the characters are confirmed to be in a relationship. Please be aware of this.
(My daughter just likes to join in the fun; she's read the original novel, but doesn't remember much of it.)
Fujii Yoru felt that as a modern young person, even if he had transmigrated, he should be more composed. But given the current atmosphere, it seemed unreasonable not to try to get some benefits for himself.
So, this orange head looks so warm and cozy, let's give it a pat. Oh~ those black hairy muscles are so nice, I'll take a second look. Wow, those eyelashes are so long, maybe I should pluck them a bit. Wow, those back muscles when you jump are so sexy!
Everyone: Is this person like this to everyone...?
(Since everyone's ending isn't too bad, there are no incredible comebacks or plot twists; it's more of a mundane slice-of-life story. Please don't overthink it; all the settings serve the content. The beginning might be a bit boring?)
