I’m a Childhood Friend, and I Want to Remain a Supporting Character, but for Some Reason I Became the Heroine’s Love Interest

When I opened my eyes, I was inside a dating sim. As the childhood friend heroine, Amatsuki Suzuna. And the one who appeared before my eyes was the listless, clingy protagonist. … Honestly, not my type. I have zero romantic experience, but being pursued is a bit of a problem. That’s right, then, if I continue to break the flags so I won’t be pursued, I can be demoted to a mob character. I’ll leave going out with the protagonist to the other girls… Hey, Heroine-san? Aren’t you a little close? Our skin is touching, and I can even hear your breathing. Um… the target of your affection, it’s not me, okay?
