This story could also be called: Did the second male lead, who could never have the one he loved, awaken after being reborn?

Going by the usual tropes, the hero is basically a male supporting character who can't have the one he loves.

A self-indulgent labor of love. I couldn't find what I wanted to read, so I had to write it myself (TT).

A story that turns the tropes on their head. Guilt isn't love, and you don't have to repay someone who saved your life by giving yourself to them! O(≧口≦)O.
