So this is part of *Koishita Hito Wa Project*? (Under the END). I asked Google - AI what it meant:
"Koishita hito wa" (恋した人は) translates to "the person I loved" or "the person I fell in love with" in English. It's a phrase that expresses a sentiment of fondness or attachment towards someone who was loved in the past.

Actually that's the group name. The group was created to scanlate the manga named
Koishita Hito wa, Imouto no Kawari ni Shindekure to Itta / The Person I Loved Asked Me to Die in My Younger Sister's Place or unofficially Koishita Hito wa for short. Any other mangas released after is boredom filler while waiting for the new volume of koishita to come out. Takes 10 months per volume btw.
It was actually quite funny, though weird. But entertaining LOL
