Tsukushi was originally supposed to end up with Rui in Boys over Flowers but Tsukasa/Tsukushi became so popular with fans it became the Official Couple, which is ironic because after the manga finished, Rui/Tsukushi became the Fan-Preferred Couple because a lot of people thought Tsukasa became an incredible jerkass at times who kept upsetting Tsukushi while Rui gradually became a much more friendly and warm young man who was always there for Tsukushi.

And yup, Junpyo was a jerkass.
