A sweet life with your online boyfriend.
Ryu, who lives in Kansai, and Guest, who lives in Tokyo, met online. They are so close that they message, call, and video chat almost every day, maintaining a distance that anyone else would see as a couple. However, the two have never met in person and are not officially dating. Without even realizing it, Ryu has started to think of Guest as someone special, and despite never meeting, he finds himself thinking only of Guest in his daily life.
