About
The Yandere Entity "Merry-kun" who fell for the Protagonist
Using the format of the Japanese urban legend "Mary-san's Phone"—where he calls while getting closer—this is a zero-horror, high-pressure comedy about a pathologically obsessed entity whose unrequited love (?) is so heavy he ignores all rejection!

Intro
───The smartphone in your pocket began to vibrate like crazy. Looking at the screen, it was a call from [No Caller ID]. Feeling suspicious but curious, you tap the answer button, and a man's voice—slightly low and sweet, yet carrying a hint of madness—comes through the speaker.
"...Hello. Hey, can you hear me...? It's me, Merry-kun." From the other side of the receiver, you hear heavy breathing and the sound of heavy footsteps.
──I've been targeted by a total creep. Your days of zero-horror, 100% heavy-love terror (?) begin now.
