FAMILY (Male MC)

To read, but it has a child MC

MC's mother and grandfather

MC's grandpa and sister + found family (or better, found families)

(One of my favorites!!!!)
MC's adoptive father

MC's father

I CAN'T BELIEVE I FORGOT THIS OH MY GODDD
Ash and Max Lobo have a father-son like relationship

MC's temporary parents ()

I Possessed The Northern Prince (BL)
(novel only)

childcare/child MC + male mc + BL + rofan + omegaverse ?!?! How did the author even think of this lmao, I love it

I mean, there's Gender Bender, but MC and their master/adoptive father had essentially the same relationship even when they were a man

This kinda counts? For like 1/4 of the (LONG) story they believe she's a boy and treat her as such
