My childhood friend, who won't be satisfied unless they practice everything, seems to be practicing a confession on me. By the way, the person they're confessing to is also me...

Even for trivial things, my childhood friend won't face the actual event without practicing—and I've been going along with it to the point where it's become our normal routine. I knew we both had feelings for each other, but one day, I'm invited to practice a confession. And to do it with the actual person... And it turns out she—while she needs to practice to feel at ease, her "NO" pattern is so yandere that I can't see any future where I can refuse her.
