"Bye bye, stupid guy" (ばいばいバカ男,Bai bai baka otoko) is the third episode of the sequel series, Hana Yori Dango Returns. It aired on January 19, 2007 and was followed by the fourth episode, "Perilous battle" on January 26.
Tsukushi Makino wordlessly leaves, after seeing Tsukasa Domyoji and Shigeru Okawahara kiss. Seconds later, Tsukasa pushes Shigeru away and orders her to leave. Tsukushi goes to work, while Tsukasa waits for her and Shigeru watches him. Rui Hanazawa suddenly shows up, so Tsukushi decides to take the day off anyway. He asks Tsukushi about her meeting with Tsukasa and if something happened. Tsukasa waits late into the night, and only leaves when Nishida comes to fetch him. That night, Shigeru visits Tsukushi, much to the latter's surprise. Shigeru spends most of the time complaining about Tsukasa's behavior and stays the night.
Tsukasa mixes up kanji again, when he explains to Shigeru that you get the "aka" (明,"aka" "clear, bright") from "akashi" and the "shiro" (白,"shiro" "white") from "shiroi" to get "akashiro", which he thinks means "obvious". Actually, the two kanji together mean "meihaku" (明白,"meihaku" "clearly").
One of the foreigners comments that Tsukasa's hair reminds him of the singer, Lionel Richie.
