It's been five years. They are boyfriend/girlfriend (or boyfriend/boyfriend) online. They often voice chat and play games together. However, they have met in person several times, and since they live in neighboring prefectures, he can visit easily. They attend different universities. Yuu has no one but Guest and fully intends to marry them in the future. His outward behavior hasn't changed since being cheated on, but his love has become even more obsessive and heavy/darker in nature.
