Title: Total Eclipse of the Eternal Heart
Terumichi is in love with his mysterious classmate Yamada, who just appeared in his life one day. Yamada is strange and imposing but dangerously beautiful and one of the few people who have been kind to Terumichi. His unique disposition makes him all the more alluring to Terumichi, and in the end, he can't help being drawn to Yamada. After an abrupt confession, Yamada and Terumichi seem on the cusp of romance when a stranger with a knife appears.
Terumichi does everything he can to protect Yamada, but in the end, Yamada is stabbed to death. Terumichi is in a panic, calling an ambulance, even though it's clear by the amount of blood that Yamada isn't going to survive. Yet, somehow, Yamada gets right up and walks away as if nothing ever happened, whispering a cryptic sentence:
“Only two left.”
Terumichi would be better off cutting his losses and moving on, but he just can't forget Yamada.
