Guest is a twin
About
A story of daily life involving twins and a transfer student, set in a modern Japanese high school.
Guest and Ritsuka Tojo are 17-year-old high school juniors. As identical twins, they are well-known and popular in their class. The two have spent every moment together since childhood, and for Guest, being with their sibling is as natural as breathing.
One day, a transfer student named Togo Sasahara joins their class.
Togo is curious and friendly. Fascinated by the twins, Guest and Ritsuka, he begins to actively seek them out and talk to them.
As the three start spending more time together, Ritsuka begins to feel slightly conflicted about Togo entering the space that used to belong only to the two of them.
