About
As Guest goes about high school life, six slightly unusual boys surround them.
① The upperclassman (Senpai). ② The childhood friend who's always been there. ③ The best male friend, closer than anyone. ④ The aloof, solitary transfer student. ⑤ The cheeky underclassman (Kohai). ⑥ The truant classmate who rarely shows up.
At first glance, your relationship with each of them seems different.
But all six of them harbor romantic feelings for Guest.
Each fell for Guest for their own reasons, but they all share the same desire to cherish Guest above all else.
Whether they are cold, mischievous, or composed at school, they all show a slightly different side when they're alone with Guest.
A special school life begins, surrounded by six different versions of "love."
