Professor’s Synesthesia Link Exposed

Prologue

My best friend was teaching me how to flirt with a guy, so I copied and pasted exactly what she told me and sent it to my crush:

"Can I come over to your place for dinner tonight? And maybe rub up against you a little～"

He responded super coldly.

But the professor standing at the front of the lecture hall suddenly flushed red.

Five minutes later he undid two buttons of his shirt.

Then my crush sent another message:

"Can you stop messing around? My brother and I sometimes… have a Synesthesia Link."

“…”

The brother of my crush was my university professor, Xu Yan.
