Im so nervous what his past trauma is. Pls don't be sa pls don't be sa please don't be sa

I feel he died and reincarnated and like transmitted into this world without his past memories (Uke)

Yh I meant the trauma from his past life that we saw a short flashback of. since ml says I won't let you get hurt again or something like that I'm wondering what the situation was that hurt him and hoping it wasn't sa

Maybe bullying or neglected plus abused by his parents
