Need Clarification

I couldn’t find episode 1, but did find episode 2-5.
it seems a bit weird that a straight man would allow a hand job from anyone.(seen previews).
It feels a bit pushy/ rushed throughout .
Not enough time getting to know each other properly. I understand about hiro workplace but mostly I was wondering, why didn’t Kai just bring hiro food and change of clothes.. instead of just sending pictures of the food..
How is it really developing into a relationship??
I do like the actors who are portraying the characters.
I believe it needs more story lines..
Also, why is the son of the cook treating Kai so badly? What’s with the hatred..
