[PC/GB?][1990-2000]Rpg with 5 stories that are linked in the end. Tragic hero, demon lord

**Platform(s): I don't remember if it was PC or gameboy

**Genre: rpg'sque, adventure/dungeons etc

**Estimated year of release: 1990-2000

**Graphics/art style: like mother 3 or chrono trigger

**Notable characters: I only remember one of the 5 stories: it's about 2 guys, A and B, who are in love with a girl C. A and B duel at a certain point to decide who'll be C's love (don't remember if this happens after). One day C gets kidnapped by some demon lord and the two guys go to rescue her. I can't remember precisely how it proceeds, but I remember that at a certain point B apparently dies under a rockslide, and A continues his mission until he discovers that B didn't die and he had actually sided and took the powers of the demon lord. A kills B but then discovers that C actually loved B, so she suicides. A now is left in despair and this story can end in 3 ways: A kills himself, A destroys the world, A... can't remember.

It was supposedly quite popular, and this hero's story somehow is linked to the other 4 plots.

**Notable gameplay mechanics: can't remember
