Itoshii Uso Yasashii Yami

At a reunion held to commemorate the closing of her old junior high school, Mio Imai (28), is reunited with her first love, Shuichi Amamiya. The formerly popular boy is now the president of an IT company, his star shining brighter than ever. Her best friend Nanae and other female classmates of “suitable age” all flock around him, and he invites them all to come have dinner with him…!? But on the day that Imai is suppose to meet Amemiya in Tokyo, Nanae is found in a very different state. Was it just an accident or…? No one knows what his true face is really like — which face will appear when the thin sheet separating good and evil is peeled away? An authentic romantic thriller!
