I really wanna know how you got to that conclusion
Well he's had this weird sadness going on where he would be considered a rival...except he's been the most supportive person ever so it can't be that.
Had a few ideas going but nothing that fit. Dead lover wasn't one of them until that last chapter where he's like 'are you testing me?'. Screams dead lover to me.
It now all makes sense. He's a little resentful of the happy relationships because he lost his. That page in the last chapter with him passing all these happy people. It's too good a fit.
I respect your opinion and it may be true, just that “are you testing me?” part I think HuanWen was referring to how pink head keeps coming back and stick to him after (unknowingly) made him heartbroken.
Ok it's got to be a dead lover right?
After this latest chapter it sure sounds like it.
