Sinful Lesson (Requested)

Park Jimin - a cold, emotionless mafia assassin - is given one mission: kill Mr. Lee, the respected professor of Bangtan University.
To get close to his target, Jimin hides behind a new identity - a calm, strict mathematics professor.

But his carefully built mask starts to crack when he meets Kim Taehyung - the mischievous, brilliant son of the university's owners, Namjoon.
Taehyung may be perfect in every subject... except math - which puts him directly under Jimin's watch.

What begins as irritation turns into tension, then something far more dangerous.
Until one night - a mistake, a touch, a memory they can't erase.
And days later, Taehyung's world shatters with one truth: he's pregnant.

Now, with furious parents demanding marriage and a secret that could destroy them all,
Jimin must face the one lesson he never expected to learn - love.
