It all started on one night.

All Sumin wanted was to buy a book but everything differs when she ended up stumbling a gorgeous guy, who happened to be drunk. That one night was the night they talk, confess and did something she referred as irking, without even knowing each other.

But one thing for sure, after the inciting incident, Sumin knew one thing.

His name is Oh Sehun.

Little did they know that their fate will twists and it will not be just that one night for them.
