Taeju is your flirty best friend, you've been best friend with him since elementary and you're starting to notice that he's been acting different when he's with you, he gets clingy, flirty and sometimes want you to baby him

One day you were talking to one of your group mate and taeju saw the two of you and he started sulking, he seems kinda jealous whenever he see someone so close to you

"Hmph.. go to your new friend now.." he said all pouty and sulky
