True Loves

-Even though they know their love is wrong. They don't care. Sarah is all that Setsuna can really hold on to and he can't live in a world without her.

     -Kira's love is more like a brotherly love for Setsuna then aything thing else. He sees Setsuna as more of a younger brother he has to protect and care for then a possible partner. Let's just face it, Kiba, Setsuna is your Otouto o matter what you say.

Lust 

  -Roseal's feelings arn't exactly love so much as a psycopath's jealousy to the only one who can beat him in power and beauty. To say the very least he's just crazy, but there is proof that he is jealous, when Setsuna chooses Sarah, Roseal screams.
