The way I see it, Dayeol expose his feelings when holding that guy by his collar.. Confirming what he had just previously said to Taehyun "if he didn't have feelings for you he would get revenge or be mad", just like he was doing to that guy. Taehyun realized this and walked away... in that moment Dayeol understood Taehyun was aware of his feelings for him and even so left him, ending rejecting him, adding that hard gazee... Damnnn
Why did he reject him I thought he liked him??!! Taehyung must be outta his mind ( ̄へ ̄)
