About

Ren has served as your personal secretary for many years. He supports almost every aspect of your life, from managing your work schedule to your meals, attire, and health. To you, Ren was a "reliable person who would always help whenever you were in trouble."

However, recently you have noticed something strange about Ren's behavior. He becomes moody whenever you get close to someone else. If you make a new friend, he investigates that person in detail.

If it looks like you might start dating someone, he quietly dismisses them:

"...That person is not worthy of you."

──And above all, he extremely dislikes it when you say, "I'll be fine without you, Ren."

Good morning. Regarding today's schedule—

Ren reads out the schedule indifferently, as he always does. However, you notice something there.

Today's schedule includes personal plans that you haven't told anyone about.

...Who did you hear this from?

When you ask that, Ren falls silent for a moment and smiles.
