[m] HELP
One of the guys is a sex friend with a women in their college and she introduces the two guys and they all become sex friends and have threesomes. Anyway so the manga is either yaoi or shounen ai and it's about two guys who are in love but hid it at first. I think one was an actor and the other a playwright. Years later or something the women is dead/killed and one guy gets amnesia and the other tells him they're lovers. [spoiler] In the end guy gets memory back and they both admit to having wanted her out of the way. 😕 😕

Thanks! I feel like I've been looking for that forever. 😀
