To prevent him from untying himself but his bro messed up when he choosed to let his legs free
I think that he tied his thumbs instead of his hands trying to hurt him less or something , and it's SOOO CUTE
Actually tying the thumbs rather than the wrists is to make it harder for the person tied up to free himself (▰˘◡˘▰) so nothing really cutish about it lol
What doesn't make sense is him thinking Hetian wouldn't try to run since he didn't even bother to tie his legs
Unfortunately my delulu wasn't wright
And he even give him the phone to make a call
why are his thumbs also tied? (≧∀≦)
