Thank youuuuu, why this scene is not showing? Iqiyi hmmm...

If i’m not mistaken, because at that timeline, they’re still in high school. They’re not supposed to date in high school, so the scene got cut out. The cheek kiss that we get was after they graduated. 

I knew smtg wasn't right when Wansen was suddenly going in for a kiss. It's not like his character to do smtg he hasn't confirmed yet, like in this case knowing if FL has feelings for him. He has always believed she nvr remembered/looked at him let alone have mutual feelings. If she kissed his cheek, at least that would mean smtg
