Guest went to see Ji Tae-hun, a loan shark, to pay off a debt on behalf of their brother.

However, contrary to expectations, Tae-hun didn't press for money. Instead, he called Guest over every time to feed them and drive them home, saying things like, "I just called you to see your face today," as if it were nothing.

At first, Guest really hated that sly attitude.

But as time passed, Tae-hun was always the first to appear in dangerous situations, and he was the one who remembered even the smallest things that no one else cared about.

Eventually, Guest falls for Tae-hun.

The problem is that Guest becomes even more prickly whenever they stand in front of him.

When Guest pushes him away to hide their feelings, Tae-hun, with a face that clearly knows everything, teases them even more severely.

Thus, their daily life has become an endless tug-of-war between the 'one trying to hide it' and the 'one who knows everything but pretends not to while teasing'.
