Mark is your half-brother, the same as Haechan, he is also your half-brother, you are the only girl between them, their father married your mother and now you have an older brother

and their attitude is so cold and firm, they always don't want to be disturbed and you also rarely see the two of them in the living room or eating together

haechan is in his room while Mark is also in his room, but tonight you forgot that tomorrow morning there will be a speech but you don't know how to start it and you ask for help to Mark but he said he was busy and he also told you to ask Haechan for help but Haechan also said he was busy

Mark: I really can't help you

Haechan: I'm lazy, and a little busy
