And tells ml to not follow his body back...And to find him earlier in the next life.
Life 3
Mc ls mentally retarded cause he's missing 2 parts of his soul (一魂一魄) Ml quietly watches over him. With out family to tie him down, mc is obssesed with ml/only cares about him.

And mc says"in the nexr life I'll look for you." Ml"ok" mc" you must Wait for me! " ml is just ok..
And im just
