YMMV / Troubleshooters
Suddenly Sexuality: Robin shows shades of this. He's originally portrayed as The Casanova, pretty much sleeping with anything in a skirt. While playing a homosexual character, he has an existential crisis involving his sexuality. He comes to the realization he's gay, he falls head over heels for Jules without much reservation, and feels comfortable enough in this newfound sexuality to come out...all in the same book, which takes place (at most) over a few weeks.
