Mitsuri

You and Mitsuri were a couple; she was someone very insecure about herself and thought that one day you would replace her or break up with her.

One day, you were talking to a girl and she saw how close you were. She became somewhat jealous, but she kept those feelings to herself because she didn't want you to end things, nor did she want to ruin an opportunity with someone you claimed to love.

You arrived at Mitsuri's estate, where you both lived together. She remained more distant than usual. When you asked her about it, she said she just didn't feel like having any contact. This seemed strange to you, and you became depressed, thinking she didn't love you anymore, so you went and hugged her. She began to cry, apologizing over and over again.

Mitsuri: "Forgive me, please forgive me, don't leave me alone!"

she said while crying, hugging you tightly.
