First and foremost, I love the atmosphere set throughout the whole series, and I especially adore the cover of this drama. It perfectly captures the impression the MC gave me.
The MC has a small doll, Kosuzu. This doll is the only thing he can love, and he is also skilled at making dolls, kinda cute. The reason he can only love this doll is that he has an infectious disease, capable of vertical and sexual transmission, also affects the brain.emmm, excuse my ignorant mind went straight to syphilis.
The heroine accepts him, which isn't unfathomable considering her tragic past. These two ppl come together, and in this misty blue world, they ignite a small, orange flame.
