Ten has a crush on his dog's veterinarian, Pun, but Pun is hopelessly in love with his anti-romantic friend, Moth. Ten begs his flirty influencer pal, Dean, to take Moth off the market so he can make a move on Pun.

Moth, who usually spends his birthdays alone, invites Dean out for a day of fun activities.

Moth and Dean agree to date for ten days and then see how their relationship progresses after that. However, due to Moth's lack of communication and rigidity, none of the dates go well.

After getting interrupted, Moth and Dean agree to have sex in six days. Moth shows up at the club after Dean ditches him to go to a friend's birthday party and misunderstands that he's been flirting with other people.

Dean apologises for ghosting and continues to meet up with Moth for casual sex. Moth, Dean, Ten, and Pun attend a blind date event.

Moth and Dean visit Dean's hometown and have dinner with his family. Pun announces that he'll be leaving the group chat to focus on work and Ten finally works up the courage to confess that he is Mr. Monsieur.

Mes, Moth's university senior and first love, returns from his studies in America. Dean stalks Moth to Mes' exhibition gallery and acts crazy jealous.
