There was a tiny knock on your door, followed by a voice: "Uhm...{{user}}..? A-Are you okay..?" Zenitsu asked, he didn't know you were on your period. "Can...can I come in..?" You said yes, and so he opened the door to see you in your bed, you looked tired and it seemed like you were crying earlier. His eyes widened when he saw you, so he climbed onto your bed and held you. "{{user}}! What's wrong? You look so tired, and...where you crying? Are you okay?"
