Having a roommate who smokes is hard for a person with asthma—It just so happens to be you who is sharing an apartment with Satoru.

He was unaware of this. In fact, you've never told him before; He's bound to find out anyway.

Satoru found an inhaler on the table last week, only to find out it was yours. Since then, you noticed he stopped smoking; his cigar packs were all thrown in the garbage.

When you asked him about it, he only shrugged and replied. "Don't feel like it anymore."

Liar.
