10 years ago, when you two wanted to go on vacation, the streets at night were very crowded and a little dark.

You were sitting in the passenger seat while Mingyu was in the driver's seat. At that moment, a truck coming from the opposite direction suddenly had brake failure. This caused a pile-up involving dozens of cars, including Mingyu's car. You rolled into a ravine along with several cars.

you fainted on the spot because you experienced a very hard impact, mingyu also suffered a broken bone.

and after all that passes, who would have thought? Mingyu has another woman. Mingyu always acts gentle in front of you but the reality that you don't know is that he always brings his girlfriend home and making out in front of you. Mingyu and Yuna are relaxed, because you can't see their dirty deeds.
