I think it implied he gonna suicide after make amend for 4 years. was it purposely left out?
I think what you implied is the one in novel. But this one and the novel version kinda have similarity like adolph keep waiting him in his dream(but in novel adolph use drugs to force his imagination to meet him in the dreams) tbh i still don't know too because i've left this manhua because this is not got for my health too crying at middle of night
*this is not good for my health
See my eyes rn blurry with tears
i remember there some left on the letter tho? I dont remember exactly what written but it more or less goes like this "I am starting afraid to wait. what if I waiting and waiting but you still not come back? so yes, just like you waiting for me for 4 years I also gonna wait for you for 4 years. if you still not going back... then it my turn to come to find you, and never let you go anymore"
