Kodoku no Yurikago

“That day”—it’s been a year since July 22nd… The scars from that day haven’t faded. Mio, who died. Kazuha, who disappeared. Left alone, I’ve been drifting through a hazy, half-conscious world. —Then, one day. Mio, the girl I thought had died in front of me, suddenly appeared again— …… Turns out, she’s just a lookalike. A completely different person. She said she’s a transfer student. But come on… that’s not something that just happens, right? [Translated from dlsite]
