Takanashi spends some quality time with his four quirky sisters; the boss, the drunk, the writer and the manipulative. Each in their own way is reliant on Takanashi to keep their family in order. White Day has arrived and Takanashi gifts Mahiru a bag of hair pins. This is the first White Day gift she has ever received. Later he runs into her on the street worried that she might attack some random male while walking around he escorts her home. On the way they run into his eldest sister Kazue. Mahiru get flustered and admits to "assaulting" Takanashi on a regular basis.

Pupura finds out about Takanashis tall sisters and is upset with him for keeping these ideal women from her. As punishment she sets him up to go on a date with Mahiru. An experiment to see how much more man acclimated Mahiru has become concludes that if she can't punch Takanashi she'll kick him in the nuts.

Takanashi and Mahiru go on their "date". The staff of the restaurant fearing for Takanashi safety concoct an elaborate plan to have him cross dress so that Mahiru would think of him as a girl and not hit him. As the date comes to a close Takanashi comes to realize his true feelings for Mahiru and Mahiru receives the compliment of her life.

Mahiru finds herself a bit too close to Sōta for comfort when he tries to stop a tower of boxes from falling on her, which leads her to become a bit fearful of him the next day. This turns into a complete freakout after she discovers Sota touching her head whilst she was asleep and stops coming into work. Later, Poplar gets locked in the freezer and initially suspects Jun, but soon finds Aoi just did it accidentally. After Mahiru doesn't show up at work all week, Sōta goes to visit her in Kotori-guise to apologise and exchange phone numbers.

Aoi, curious about Sōta's delayed reactions, is tasked by Yachiyo with taking a photo of Hiroomi for an album. Meanwhile, as Sōta and Mahiru go on their date, they are interrupted by Mahiru's father, who Mahiru hits when he starts insulting Sōta, managing to work things out with him. Later, Yachiyo announces her resignation to the rest of the staff, with Sōta encouraging Popura to do her best as the next chief before being mysteriously abducted.
