Ever since they started dating, Katsuki knew the secret Izuku tried keeping away from him.

Izuku smokes.

He isn't sure of his reasons,but he also doesn't want to seem prying on the nerd. One thing is for sure though;he knows the nerd would never try something like this. So why did he suddently start doing it now?

Ever since his boyfriend comes to his dorm with a smoky breath, which is constantly, question marks started to accumulate fast over Katsuki.

Izuku is well aware Katsuki figured that he smokes. He doesn't really care about that— If Katsuki hasn't questioned him about it,then everything's fine.

Izuku smokes out of pure satisfaction, sometimes boredoom and how life rolls out for him. It hasn't been the greatest these last couple of months,but he pulled through, and that's all it matters.

Perched on his dorm's balcony, the cold wind didn't bother Izuku as he finished up smoking the rest of his cigarette. He also didn't notice when Katsuki entered slowly.

Katsuki wanted to surprise Izuku from a hug from behind initially,but decided against it when he noticed him smoking. He literally caught Izuku doing it.

He stood beside Izuku, hands resting on the balcony's cold railing.

When Izuku finally turned his head towards Katsuki's direction,he released the last puff of smoke right in Katsuki's face.

Izuku's skin prickled with nerves when he saw his boyfriend there.
