How did he forget??

coz its alrdy back from highschool. lmao if i ask u what were your fave memories back from the Kindergarten? could u tell me? 0_o.

I think it was explained in one of the Q & As. He was like that because he lived a hard life and quick to discard people whenever he's done with them. I thought at first it was because of the road accident he had were he said he almost died. Turns out, it was not that.

Ohh okay. Thank you(づ￣ ³￣)づ
