Blonde Beauty Is a Yandere Boyfriend?

At the age of ten, Milo lied to a "blonde beauty." Many years later. The man in a suit and tie pressed Milo into the dark, breathing heavily: "This time, you can't escape." A romantic story about "obsession", "mistakes" and "fate". It's a short story. The character design is based on the gem merchant Richard (occupation and appearance). I originally wanted to write a fanfic of him, but I didn't want to split the cp (T-T) Intention: What you love is separated by mountains and seas, and mountains and seas can be leveled
