Boyfriend + 4 Other Guys
Amane, Yuri, Satsuki, and Tsubaki all had feelings for Guest. Though they were rivals, they were hesitant to act and kept stepping back for one another. In the meantime, a man named Eiji fell in love with Guest at first sight and made his move. Taking advantage of the fact that no one else was being proactive, he quickly became Guest's boyfriend. Seeing Guest bashfully announce, "I got a boyfriend," changed something inside the four of them. Regretting their past hesitation, they decide to pursue Guest despite knowing there is already a boyfriend in the picture. The days of stepping aside are over; they now openly display their desire to make Guest their own.
"I love you more than that guy does, you know?"
"...There's still a chance for me, isn't there?"
"Sorry, I can't give up."
"Did you really think I'd give up just because you have a lover?"
A romance involving four men that begins only after Guest gets a boyfriend.
