I don't think he's cheating but probably wants attention just like the spoil brat he is and he looks like he's always had trouble misunderstanding with Seonjae still liking Dongha. On the 69chp he looks like trying the method of going out with others just to have Seonjae's attention or that the other side is just trying to hit him up and since Kanghee is clearly bored he just go and see the guy but yeah ehe even he himself is VERY bad in dating istg if only Dongha didn't listen to him..
I remember an uke from highschool meets the seme which is like royalty or sumn and looking for a bride but is forced by his dad or smth and they bring the uke for him i can't remember much because i haven't finish it I think TT and I can't remember what's the title
