I am still expanding my anime, but what I have watched so far,
Anime Boyfriend- Fushigi Yuugi character Tamahome/Taka
Anime Girlfriend- Oh (Ah) My Goddess character Belldandy
Both loves the significant other, truly. There is no underlying agenda, malicious motive or clingy neediness. It just seems pure and raw with maturity to it. Through thick and thin, they still love each other. They both have inner and outer beauty.
