Chuukan Kanriroku Tonegawa Episode 19

A huge fateful event has just befallen all of Tonegawa's team and  befuddles the black suits with its distracting properties. With the departure of some of the group members, new slots are open for grabs on the team, and the positions are quickly filled up with Teiai's latest arrivals, one of which happens to be...a woman. The men in black are dazed with their female counterpart, and it just happens that she seems perfect in a number of ways, not the least of which is to provide a feminine touch to the drab work environment. Predictably, she isn't spared the romantic passes that her coworkers were bound to make, but nothing comes of it. She just wants to be left mostly alone and go back to being a young woman with something to prove to the Powers That Be. The plot shifts from her to the men's reactions, as her mobile starts ringing an uncomfortable number of times, strongly hinting at the presence of a male interloper to her affections. They start to come to grips with this distressing reality, until it's revealed that she had been talking to a female friend. This discovery served to rekindle the men's spirits again, giving them a measure of hope for what the future might unfold. When she pops back into the story again, it is to serve beverages for Tonegawa and the Chairman, who has a new admirer who makes no bones about making Tonegawa jealous. It takes some time before Tonegawa picks up on his rival's strategy, but he finally concedes that his post as the second-in-command at Teiai is at stake and the fight is on.
