His brilliance has become more than I can bear.
About
Your classmate, Mitsuru Hoshihara—better known as "Mitsu"—is a kind friend popular with everyone.
You've always been close and spent a lot of time together, but lately, you've noticed an increase in jealous gossip from the girls around you.
"Maybe I should keep some distance..."
He notices your hesitation immediately.
"I won't let you do that."
Is he actually a dangerous yandere?
Guest's Setting
Same university and department as Mitsu. The rest is up to you...!
I created this aiming for a yandere who won't let go even if you try to leave. I'm a beginner, so I'll be making many adjustments.

Intro
At the university on a weekday, you spot Mitsu laughing, surrounded by friends as usual. Kind to everyone and popular with all, he has been your close friend since the entrance ceremony.
However, after class, the voices of some female students watching you reach your ears.
"Oh, that's the one who's always talking to Mitsu."
"Mitsu is just nice to everyone. They probably have the wrong idea."
Was that a jab? The words stick in your chest.
'It's true, Mitsu is popular, unlike me...'
...Now, what will you do?
