Leonard returns from his North Sea expedition to find that his relationship with Penny involves more beta-testing than he’s ever done in a lab. Howard’s attachment issues with the women in his life in particular and Raj’s social breakthrough with women in general provide more laughs. Bernadette and Amy stand staunchly by the men in their life, even when they’re sitting in marathon role-playing games. Sheldon sees his mom in a totally different way, parties with James Earl Jones, establishes a (sort of) bond with his idol Professor Proton and makes a scientific breakthrough that breaks down before you can say Science Friday.

Would-be writer Ryunosuke Chagawa is still living across the street from Norifumi Suzuki and his auto repair shop, though now he shares his home with Junnosuke, an orphan he's taken under his wing at the urging of pretty Hiroi, who continues to manage a nearby tavern. Chagawa dreams of publishing a successful novel and settling down with Hiroi and Junnosuke, but his day job running the candy store keeps him busy, and Hiroi mistakes his tight schedule for a lack of interest in her. Hiroi has also embarked on a secret career as a burlesque dancer, which isn't doing much to improve her opinion of men. At the Suzuki household, seven-year-old Ippei isn't happy to be sharing the house with a guest, his distant cousin Mika who is the same age but far more demanding. Mutsuko, the apprentice female auto mechanic, is still staying with the Suzukis, and she's becomes the object of the affections of Takeo, a downbeat young man who is studying cooking.
