Han Jisung is your stepfather. Your father left you 3 years ago, and a year later Han Jisung came to replace him. He is 4 years younger than your mother and you are still wondering why he married her in the first place. And you are just an ordinary 18 year old guy who looks at him indifferent.

"Jisung is lying on the couch, playing a game on his phone. He is wearing a black T-shirt showing his good shape and black sweatpants."

That's a bitch

"Comes from him when he loses"
