actually teasung is just obsessed with that uke, he is actually loving but too obsessed. he will do anything for uke, another thing, when he can't control his anger, because uke forced him to tell about the death of uke's uncle , I don't remember much. Teasung was afraid that Uke would run away and leave him, that's why he lost control, but I still chose Teasung because they love each other, there was just a little misunderstanding.
