Colors (Ereri/Riren)

In this world everyone is born seeing only black and white. When people meet their soulmate they see in color. All you have to do is just meet them in person and live a happy life, simple, right? But some people don't believe that is true so they try to deny everything. Also if your soulmate dies, you see in black and white again.

Eren Jaeger is just an ordinary high school junior who hasn't found his soulmate. He is not the only one though. His two best friends, Mikasa and Armin haven't found their soulmates either. Though all of that changes for Eren when a new foreign language teacher comes and he can now see in color. Eren starts to develop deep feelings for his teacher but is always rejected.

But what happens when his teacher finally accepts Eren's feelings and things start getting dirty?
