Huh ? But he's more than single and free, he is not Yuyang's old crush. Do you really think they would have their current relationship if Huanwen and Lin Xiang were the same person ? When Yuyang barely just moved on and panicked when Xiang was mentioned ? And also the fact that Xiang is almost never at school (as it was mentioned during the double movie date)
And from what we saw Huanwen is probably the one who will make a move first.
