"Since there is no man or woman in my past, there is no possibility that such a person would appear in front of me." REALLY, BRO?! Really?! You have until 2022 to prepare for Hatano's return! And you better not break that poor boy's heart!
I know that this story is not supposed to go in a truly romantic direction and I love it for what it is, but I can't help but cheer for Hatano and hope that the MC might develop feelings for him. At the same time, I would also love it if the MC found a sweet girl to fall in love with. It's quite a difficult choice.
