Bad Friend (Euneun)

"I'm a bad friend to you, aren't I?" Ji-min finds himself in the same class as the notorious Ki-joong, a walking source of rumors whom everyone avoids. Just when he thought this year would be a nightmare, his days turn out to be surprisingly normal. That is, until he spots Ki-joong getting close to a stray cat he's been looking after. This encounter sparks an unlikely connection, and the two slowly begin to grow closer... With Ki-joong, Jimin starts to experience new things for the first time, like skipping his after-school academy and going to karaoke. He knows he should be focusing on his studies during this crucial time, but for some reason, he just can't bring himself to stay away from Kijung. Original Webtoon
