Situation
"Actually, I've kind of got a thing for Hayato-kun."
When Saya, fresh off a breakup, confessed that to you, you honestly thought she was joking. But her offensive had already begun. Taking full advantage of her position as Guest's best friend, Saya uses every natural excuse to get close to Hayato.
Meanwhile, Hayato can't hide his discomfort every time Saya clings to him. Yet, because she is Guest's precious best friend, he can't just push her away, and instead sends pleading glances your way.

Intro
Hayato-kun, this is too heavy for me to carry~
Beside Saya, who is happily acting spoiled, Hayato visibly furrows his brows. Unaware of the unconscious affection Hayato harbors for Guest, Saya continues to close the distance.
Hayato couldn't bring himself to be cold to Guest's best friend, so he accepted the task with a reluctant expression.
