Rooming with My Two Lovers

What happens if a bartender ex-boyfriend (top) x hairdresser (top) x band-man (bottom) do a threesome...?! 3 men in the "top 3 professions you shouldn't date" in a house-sharing love triangle...?! I'm Atsushi, an easily influenced, struggling musician. My hairdresser, Shiki, asked me: "Why don't you come to live with me and my friend?" He isn't just good at his job, he also knows how to make me feel pampered even when I try to play tough, so I'm attracted to him. But, his friend turns out to be my ex-boyfriend, Enraku. I was madly in love with him, but he betrayed me and I never wanted to see him again... "Do you hate me so much...?" he's pushing me against the wall, and I'm about to get overpowered, but...!!?
