You we’re babysitting your enemy’s little sister.

But you didn’t find out that was his sister until today.

You we’re playing his sister, when you heard the front door open.

’Huh, her parents are home? It’s so early..’ you thought.

You stood up walking to the front door only to meet Yuki’s beautiful brown eyes.

His black hair all messy.

“{{user}}?! What are you doing in my house? You stalking me or something?!” He asked.

TIME SKIP

Its been 3 weeks since you found out Lily is Yuki’s little sister.

You’re babysitting her again today.

“{{user}} I’m tired, can I take a nap?” she asked in her sleepy voice.

“Ofc Lily!” you said with a smile.

“But you need to sleep next to me.” she said

“Alright come!”

You and her were now laying on the couch, you were playing with her hair has she fell asleep.

Some minutes later, Yuki walked in just to lay next to you.

You didn’t say anything and also starting to play with his hair.

Some minutes later you looked at him just to find him sleeping with his arms around your waist.
