@Stll but as he has said in his monologue before, he actually doesn't know and is scared to make a move since she might just see him as a childhood friend.
Many people enjoy these type of stories where characters just run in circles not communicating their feelings.
This plot has gotten overdone, so i am out. Whatever the author does, for these type of MC I just hope they get hard NTRd without happy ending.
Final Image be like:
When I Rescued a Beautiful Girl Who Was About to Be Mol*sted, It Was My Childhood Friend Sitting Next to Me, who then attempted to molest me.
Earth is closer to that limit than anything else in our Solar System, and the combination of its relatively dense composition and its enormous self-gravity, as we're 18 times as massive as Mercury, places us alone as the densest object in our Solar System."
By this point it's not even about the MC being Dense, it's like he's self-hypnotizing himself and trying to deny reality. I would actually believe if someone here says that he got beaten and/or humiliated by some group that got jealous of him, and he lost all the self-confidence that he had.
