Sorry bucko. You missed your chance. Right now I don't think the guy is an asshole cause like sure he might have rejected our protag, we also don't know what the rejection looked like. He could have just gone sorry man I don't feel that way. Also he doesn't know 100% the protag has started dating someone else. He might realize now though. I can't bring myself to hold someone's uncertain feelings against them.
Wait what did you mean by "will he reciprocate my feelings"? You're dating someone else remember??? What feelings are you talking about you're making me angry uke
So, Nakano knew his friend's feelings toward him ?
And yet he introduced his girlfriend to him ? Not cool.
Maybe he's flattered and conforted by somoene who loves him (unrequitedly), and he doesn't want to lose that...
