Best workplace senpai and wingwoman.
She could have easily been the stereotypical man-hating psuedo-lesbian who exists to stretch out the main plot or continually attempt to steal the MC from the FMC, but nope, she's actually supportive of the entire thing and does what she can to help the two connect. That she doesn't understand the concept of personal space is just a meh trait compared to other secondary rom-com manga/anime characters, we have yet to get some kind of backstory regarding how she met FMC and why the skinship between the two is so casual, so I'm reserving judgement until then.
