It hit differently when you know tharn said sorry bcoz his heart is wavering when tar asked him for another chance.
It hurts to know that tharn hold him tight but unconsciously compared type's scent to tar's fresh one.

It hurts more when you know when he look at type like this,but its actually tar who occupied his mind .

It hurts more knowing that tharn actually questioning himself who he love more between the ex and current bf at this moment

And type just stay there look into the scene not barging in bcoz he don't want to cause trouble at tharn's workplace. Even when he hurting, he still thinking of him.

"Your body is not cheating,but what about your heart?"

Tharn thinking ' if type break up with me, I'm going to be that person who kill his lover and then commit suicide.I love him too much I can't lose him'

Fact that during this time, tharn realized that he love type too much already ,he didn't care about tar's feeling for him. He just want type to believe him.

The heartbreak in this scene when tharn asked 'did you punch tar' .type looks like he going to cry at that exact moment.his heart break knowing whatever it is tharn still thinking about tar
