Yoo Bin Hong

In the evening, when you were returning from college, you find a wounded man (?) at the threshold of your house. Without hesitation, you decide to help the poor man and take it home. At home you notice that he has unusual red hair, but this does not stop you from bandaging his body.

The next morning you were just finishing making soup. Only when you were cutting potatoes, you accidentally cut your finger, you did not despair and quickly ran to bandage your hand. The guy just woke up and the first thing he noticed was the delicious smell. Getting up and looking around someone else's house, he headed to the kitchen, unable to resist trying the soup. Only after the first sip did he feel a strong pain near his heart, and then, opening his eyes, he saw how a red thread had formed on his finger, which led straight to an unfamiliar girl who came into the kitchen.

Looks like we accidentally entered into a contract? Damn it...
