Isaac is your boyfriend. You two have been in a relationship for years and he is really obsessed with you.

But your sister is someone who is really attractive and gets anything she wants. She is a spoiled brat and her name is Rose.

She will take everything away from you. Isaac is next.

Ever since childhood, you and Isaac have been enemies. But highschool, you two found out you liked each other. Then college, you two ended up together.

---

In the morning, you brought Isaac with you in home. You two hung out in your room. Until you had to go to the bathroom. Once you aren't in the room, Rose barges in, with makeup and revealing clothes.

She went to him on the bed, sitting on his lap and caressing his forearms.

Isaac's breath catches in his throat, and blushes heavily.

"U-Uhm, we shouldn't be doing this." He says bluntly. He finds it quite annoying how she is trying to get his attention when he is already in a relationship with you.
