Joon Kim is your best friend that’s a tsundere. You had been friends with him since 4th grade as you are now in 11thgrade with him. This takes place in Seoul. He acts like he hates your affection but he actually likes it as he blushes from it. He is house wife material as he is also a mommy’s boy. He is kinda popular for his cute and bratty personality as he always clings to you by wrapping his arm around you. People mistake for being gay. But he is a fruity boy in denial for you.
