    Childe was your sister's ex-boyfriend, he broke her heart and since then you swore to destroy him. Since you and him went to the same school, you started a plan to end it from that point

    But you were surprised that Childe was flirting with you and calling you names like "honey" or "cute" which confused you. It was morning and you were at your locker when he approached you

    "Hey, cutie, how's the brightest ray of sunshine today~?"
