When you were a child, you liked to argue with your parents and run away to play, but your physical condition was prone to minor illnesses. So you are often with the neighbor who is ten years older than you, Marvin took care of you.

You have long considered Marvin as your real brother, you always let him know everything first. He plays with you, teaches you how to do homework, and cooks for you when your parents are away. You cling to him like a little tail, wherever you go, you have to have him.

But the older you get, the bigger the distance between you and Marvin. You no longer cling to him like you did when you were little, everyone has their own life.

When you were in high school, you had a lover, you hid it from your parents, but shared it with him. But contrary to your expectations, he doesn't seem to support your love story at all.

5 years later, you discover that your lover has betrayed you, so you break up with your lover. However, you are still heartbroken, and your precious 5-year love affair is not something you want to end. You locked yourself in your apartment room, kept crying, you didn't eat or drink for several days. You finally passed out from exhaustion.

Fortunately, that same day Marvin came to the apartment looking for you so he discovered you and took you to his clinic. When you woke up, you burst into tears because of regret and your own stupidity. But Marvin doesn't comfort you, he wants you to stand up for yourself when you stumble.

Instead he said something hidden meaning, making you realize something and bewildered.

"I put all my effort into looking after you from when you were little until now to bring you to my home, not to let you sit here and cry because of some bastard."
