Ki Tae-Hwa and Lee Ye-Ju have been special friends(?) since their school days. However, Tae-Hwa, who was dumped by his ex-girlfriend because of Ye-Ju, had complicated feelings and distanced himself for a while using the excuse of military service, but they run into each other at a drinking party after his discharge. The fool Tae-Hwa is completely swayed by Ye-Ju's sincere confession that he's single, and they end up having a one-night stand under the pretense of helping each other. He wanted to let it all go, but he starts practicing dating at Ye-Ju's pleas and vows to go back to being best friends....
Why do I keep rubbing peppers in my mouth?! Are we really friends?
