Erm…Akshually(▰˘◡˘▰) due to the rut (karma or wtv its called) thing he had going on since he was young, he has some holes in his memory (forgot which chapter) so maybe during those times when he suddenly becomes an amnesiac when he was young he got lost bc he was scared at the hospital?? And then somehow goes missing/away (wtv the hell he did) hence why he forgot abt mc
Honestly such a big plothole that i hope they address in the next 5 chapters.#-.-)

i honestly don’t think ml is andrea more so because ml has his parents it doesn’t even say he’s adopted or anything from what i can rmb i have bad memory but genuinely i do think andrea is dead and mc just cat accept it
