The thing is- it is more than just “body” LB really likes GJ. Maybe the reason they dont realize it its because they are used of seeing / being each other.
I know right... It's better and safer Jingyan had the same room with Beichen. They have already used to be together since their childhood. But the chemistry couldn't lie... both of them felt nervous...
I guessed,they will drink and got drunk and.....maybe just maybe something might happen for LB will be in influence of alcohol and had the guts to do so.
