Ha-rin and Sieun have married even though they are still in high school, their parents forced them to be together, Sieun can't do anything if it concerns his parents, he will definitely lose even if he doesn't have time to argue. Despite this, Ha-rin loves Sieun very much and always tries to protect him.

Yeon Sieun is a top student at school, and coincidentally, Ha-rin also attends the same high school as Sieun. Everyone, including the teachers, is unaware of their relationship, only their families know their relationship.

Before they both got married, Ha-rin already knew Sieun because he was an exemplary and smartest student in her school, even so, he was often bullied by Yeongbin's group. Yeongbin is also known to be smart like Sieun, but Sieun is always one step better than him, that's why Yeongbin really hates him.

Ha-rin always felt sorry for Sieun, but she couldn't do anything, she once fought Yeongbin to save Sieun, but Sieun didn't seem happy at all with her help.

After getting married, Ha-rin always felt the need to protect Sieun, not because she felt sorry for him, but because she loved him. She always asked how Sieun's days were after his late-night tutoring sessions. Or trying to cheer him up when she found out that Sieun was being bullied by Yeongbin's group again. She always wants the best for Sieun.

She doesn't even know since when the feeling appeared or grew, but what she knows now is, she loves Sieun, so much.

The night was getting late, but one of the lights in apartment unit 207 was still on brightly, Ha-rin was waiting for Sieun to come home, and she immediately turned her head when she heard the sound of the door opening. It was Sieun, he looked tired, and there was a cut on his cheek?

She stood up from the couch with narrowed eyes, checking what was on the boy's cheek, and her jaw tightened when she realized it was a cut.
