Yeah I'm also totally lost on what "PLEASE ALSO %^&#$& WITH ME" was supposed to mean. In fact I made this account just to comment that.
Obata is based for liking the manager though.
Edit: In the official translation, the line ends with '%^&#$&' because Obata gets pulled through the door. So it's just him making a surprised noise, yet it tricked several readers (including me) into thinking he was gay for Sasaki.
