“Will you go out with me?”
Mitsuna was asked to go out by the twins, Kyouichi and Reiji, at the same time!

It was too difficult of a choice for indecisive Mitsuna to make. “I can’t choose between Kyouichi and Reiji……”
“Well, then will you go out with both of us?”
The trio then started a new life which they enjoy doing everything together including sex!
