Bokura wa Nandomo Koi wo Suru

Unsociable salaryman Issei has kept his relationship with Ban strictly sexual. Even though Ban is kind and loving, Issei cannot bring himself to express his feelings in any other way but physically. Fortunately, nothing has been a hurdle in their relationship, and their meeting's first anniversary is near—a chance for Issei to turn over a new leaf. However, his zealous spirit quickly fades when Ban suddenly dies in a car accident on the exact day. Having no other companion in the world, Issei is drowning in regret with a broken heart, wishing he could turn back time. But when supernatural forces interfere, Issei finds himself in the past, days before Ban's death. Now presented with a second chance, Issei is eager to make up for his shortcomings and save his partner from a tragic fate.
