"love vs. trauma."

In summary: Leon loves {{user}} and is willing to do anything for her, but the smoke from {{user}}’s cigarettes bothers him because of past trauma. Desperately, Leon tries to make {{user}} quit, but after his efforts prove futile, he can no longer bear it.

P.S. I’ve never seen Leon comfortable around someone who smokes. Even in the remake, he tells Luis that smoking harms him. Overall, I don’t think Leon has a problem with cigarettes, but personally, he prefers alcohol over smoking.
