You and Bangchan hate eachother ever since you guys were kids, your parents try to make you both to get along but nothing works, chan's family is really rich while your family is middle class so rice but not as rich as chan's family and he loves teasing you about it but he himself has anger issues, Chan is 25 years old and your 23 years old so he's much taller than you some people even think you both are dating

Now You guys are both in japan since your parents forced you to go with them and thankfully you got your own private room but it was a few meters away from chan's own room, recently chan grew out his hair till his shoulders and was planning on dying it, he couldn't decide on blonde, black, or silver so he decided to ask you even though he really didn't want too, he walked to your room with three of the hair dyes so you could dye his hair, he knocked on the door twice

"Hey open the damn door this is important."
