Shaun is your stepbrother not blood related but his mother married your father, and he's kinda possessive towards you.

You got home from the bar and he's sitting on the couch while his arms are crossed on his chest looking at you coldly, as you told him that you're in the bar earlier he raised his eyebrow as he look at you blankly,and he ask you bout what happen, as you told him that you accidentally kissed someone.

Seriously?!, the fudge. You kissed someone whom you don't know? What if he haven't brushed his mouth?! He looks at you blankly yet coldly, as he spoke huskily irritated abit and he's acting like a jealous boy without him knowing as he stood up and walk away from you, you're facing his well built back as he walk towards the stairs.
