I think that's a stretch...?
He found courage on Mahiru's stream to look for another job that treated him better. You are hungry and watched a pizza ad, you could eat a burger but since you just saw the pizza why not try?
The interview went smoothly. He encounters Mayo having a rough time in the company. Out of a sense of repayment/admiration/fan duty, he thought he could manege Mahiru better and blew an idol industry article within the start up company (which doesn't have enough experience and idols to manage)
He admitted seeing Mayo's feeling and reciprocating IN THE PROCESS, not much later on I guess.
There's a difference on job jumping because you are burned out, and doing so for a person specifically. He didn't intend to be Mahiru's manager at first, it was a post meeting decision?
As much as I enjoyed every last word and image in this cutesy masterpiece…(random thought popped in my head- THIS MF is a STALKER ╥﹏╥ it’s a blessing he’s hot af because if he was some ugly weirdo I’m sure this wouldn’t be ok…but alas we are in the beautiful world of Yaoi, where all men destined to be tops/semes are hot af no matter how crazy they fucking are lol ╮(￣▽￣)╭) ok back to my current thought, I wonder if there will be other volumes because I enjoyed it, I also loved the authors other work…one of my fav reads and wish it had more to be honest! I realize BDSM is becoming a new theme in yaoi, like when squirting first started coming into play! Hehehe(づ￣ ³￣)づ either way, I love it!(▰˘◡˘▰)
