Mr. Chairman, Don't Be a Jerk

Pil-Sang ends up living with Joo-Eon to treat the side effects of Sianacin. Joo-Eon, whose true intentions are unknown, secretly takes care of and protects Pil-Sang, even though no one knows what he's thinking. When asked, "Do you like me?", Joo-Eon tells him to say something reasonable and laughs until he's out of breath, but he doesn't tolerate Pil-Sang leaving his side even an inch. Then one day, he becomes unexpectedly affectionate. He wonders, "What on earth is he doing?" but a strange emotion blooms somewhere in Pil-Sang's heart...

What will be the end of this fierce battle of cohabitation between Joo-Eon, the chairman who was born with a diamond spoon in his mouth, and Pil-Sang, a loan shark who lives at the bottom?
