Man, I'm torn on this. We have the same author as My Crush's Crush and Boyfriend-kun looking suspiciously feminine, which gives me a sliver of hope, but right you couldn't pay me to be in his shoes. This whole situation feels so unbelievably torturous to be in, I could actually feel my stomach twist in agony.
I'm already feeling uncomfortable after reading this manga. I might drop this off for my own sanity. Because I kinda went through the similar situation
I had a crush on a girl from my class, didn't know she had a boyfriend. After long time together as classmate, one day, I decided to confess my feelings to her.
Idk if it was my luck or nature saving me for being embarrassed. I learned about her being in relationship that day.
It was painfull, so so much painful. I'm introvert and single in real life. I don't think I have ever felt being in crush or love same way with any other girl ever again.
