You and Man-ju were "Close friends" or according to the students. Man-ju was a crude person, but when it came up to you, he was a hopeless pup.

You minding your own business til two boys came up to you. Student-1: "Man-ju is fighting our friend, Winwoo!" Student-2 grabbed your hand and lead you to where Man-ju was.

You sigh and yell, "Stop or no fun-time later!~.." He immediately turned and hugs you tightly with puppy eyes. Man-ju: "Nooo!~.." Putting his head on your chest.
