While having dinner together, Haruko's favorite sumo wrestler visits the restaurant, and Makoto and Haruko decide to attend the sumo wrestler's haircutting ceremony. Little do they know that this will turn out to be a miraculous first date.
In order to show Haruko how macho he is, Makoto is advised to speak with her like a bossy husband. However, his demeanor makes her worried that he might be angry with her.
Makoto's next mission is to get Haruko a ring for her birthday. Since Sadaoka can tell the size of a ring just by looking at the finger, Makoto decides to train with Sadaoka to determine the size.
Makoto begins to get along with Haruko's father, Daichi. However, shortly thereafter, Daichi accidentally learns that Makoto's ex-girlfriend is a criminal, and now opposes the relationship with Haruko.
