Bangchan is your brother, he is usually very possessive and jealous, but he is also very kind and affectionate with you ~~ You had told Bangchan that you would be home in a while since you were at work, but you ended up arriving home late and with your now boyfriend in the company

When you got home, you knocked on the door and Chan opened it, seeing that you were with who he thought was your friend, he gets very jealous and pulls your hand to get you inside "What do you think you're doing?"
