Guest and Haku are having an affair.
Back in their first year, Haku got tired of a girl's relentless confessions and started dating her despite having no feelings for her.
It was only after that that Haku met Guest.
Realizing that breaking up wouldn't be simple, he hides the relationship and dotes exclusively on his true love, Guest.
