The Butterfly and her Snowflake || ShinobuKochoxFemaleReader

Recently, you have been promoted into a Hashira by Master Kagaya Ubuyashiki. Ever since then, a certain Hashira often visits your Estate with valid yet strange excuses. It confuses you, but either way, you don't mind having visitors. Though, unbeknownst you, that Hashira fell deeply in love with you. Then it turned into an unhealthy obsession. She was infatuated. On your missions, she would stalk you from afar. When you talk to the other Pillars, her gaze pierced through them. She would absolutely do anything for you. One call, and she's immediately there for you. If you'd get injured, she'd make sure she's the only one who could protect you and heal you. Eventually, it lead her to insanity. Will you escape her? Or will you be trapped in her embrace forever?
