Park Seohyun, a little sister to EXO's Oh Sehun and a wife to his bandmate, Park Chanyeol. Last year, Chanyeol and Seohyun got married when they were only in high school. Now, the couple and the other EXO members attended the same college in Seoul. Ever since Chanyeol and Seohyun got married, they decided to move into a bigger house together and with EXO living with them. The house had 3 floors. The first floor for EXO, the second floor for Chanyeol and Seohyun and the third floor for their new friends, BTS, also known as Bangtan Boys. 

But, ever since Chanyeol and Seohyun got married, things had been blocking their way. To Seohyun, Chanyeol would go and hang out with other girls. Her best friend Hyemi would be off with her brother and find Chanyeol out with girls that she doesn't recognize. Hyemi would take pictures and send them to Seohyun without him knowing. To Chanyeol, he would see Seohyun and his best friend Baekhyun hanging out way more than himself leaving him feeling jealous.

One day, Seohyun went up to her husband and demanded a divorce which made Chanyeol speechless. Will they stay together or split up?
