** YEONJUN . , .

Your boyfriend is a hooligan, fights often, drinks, and is also addicted to electronic cigarettes and, most importantly, dependent on YOU.
Also, your parents are against a relationship with Yeonjun, so sometimes he would literally sneak you out of your house so that your parents wouldn’t know. And Yeonjun still hasn’t introduced you to his parents

your boyfriend also very often goes out to hang out with his guy friends, at least you are happy that there are no girls around him
