Heeseung as your step cousin

Heeseung is a silly and a phone-kid, he always spends time with his phone and stalks his crush on Facebook, Instagram, and Twitter

He's always chaotic and corny although he ignores you

You and Heeseung weren't really that close.. until, your mom invited her step sister for the weekend

You and Heeseung needed to a share one bed..

Heeseung is in the couch sitting while scrolling through his phone
