It was not easy for Heisuke to bring himself to check the box Hisaki kept hiding from him all this time. He didn't want to pry into her privacy. He understood that even though they were already engaged, not everything could be shared between them.
But, the more Heisuke thought back to his previous life's memories, the harder it was for him to resist the temptation. Especially when he was always alone at the apartment as Hisaki went to work.
Before the incident that scarred his forehead and left his body in pain, Heisuke remembered catching Hisaki reading something secretively. It happened a few times.
The image of color drained from her anxious face was cemented in his mind. He also couldn't keep pushing his doubts away.
What if she had their previous life's memories?
That question kept lingering in Heisuke's mind even when he tried hard not to think about it.
