There's be and there's he, but there's more he, and it's also arguably a He finale. The he part of the grand finale of the drama "Please Answer 1998" is that the lovers are married, though Kim Jung Hwan remains single, and the be part is that the double-door cave where they've been living is demolished, and everyone in the hutong moves away.

It's raining and Sun-woo goes to pick up Bo-ra, and holds her close, asking her about wanting to get married sooner rather than later. Deok-sun imitates Lee Young-ae and uses orange lipstick, and is taunted by her younger siblings and Pearl, while Ah-taek keeps complimenting her on her beauty. Deok-sun's father has a fortune and discusses moving with Jung-hwan's parents.

Sun-woo and Paula were kissing goodbye when the adults saw them. The adults were frozen and they fled in a panic. After so many years of living in the neighborhood and having the same surname and nationality, the adults found it hard to accept what happened to the two of them.

Sunwoo's mom urges Sunwoo to think about it, and Sunwoo says he's been with Paula for six years and asks his mother to understand. Paula is also convincing her parents that she wants to marry Sun-woo.

Jung Bong and Man Ok meet again and he bravely takes her hand. After meeting Man Ok's dad on the road, Man Ok hesitates for a moment and also gathers the courage to let Jung Bong get to know his dad officially. Zhengfeng decides to give up his study path, which is not suitable for him, and goes to work instead. A few years later, he became one of the most successful people in this alley.

After the adults have accepted Seon-woo and Bo-ra's affair, the news reports about Deok-seon's romantic relationship with Ah-taek. Deok-seon's mom doesn't want to believe it because Deok-seon and Ah-taek have always had a good relationship. Besides, she doesn't want in-laws stacking in-laws. Deok Sun and Ah Ze did not admit their relationship to their parents on the surface, but secretly they were stable and continuous.

Paola and Sunwoo are getting married tomorrow. The parents each lamented. The next day, when the bride and groom exchanged rings and thanked their parents together, Paula cried and Deok-seon cried as she watched her sister from below. The kids are all grown up and understanding. Paula and Sun-woo quietly handed their father a thank you note before their wedding trip, and he howled as he watched behind his back.

Aze's father moved first, then Jung-hwan's family, and finally Deok-sun's family out of Ssangmun-dong in order to live in an apartment building when he wasn't too old.

Time passes, and the middle-aged Asawa-Deok-seon couple reminisce together about those days. Asawa suggests going back to Shuangmen-dong to see it again. The streets of Shuangmen-dong are deserted. Deok-seon sighs that as people grow old, so do the hutongs, just as the youth that was once there is no longer there, and the past can never come back. However, DeShan's tearful eyes, as if the four young friends of that year are still sitting in the room waiting for her, waiting for her to watch "Heroic" together, those familiar movie images, that familiar song melody, they once again sing together. The voices of the adults urging them to come home for dinner rang out once more.

Deok-seon realized that nostalgia for the years of Double Door Cave was more than just nostalgia for his younger self than he is now, but more than that, it was nostalgia for his father and mother who were young then. The youth of his friends, the youth of all the people he loved. A formal goodbye to all of them. Goodbye, youth. Goodbye, Double Door Cave.
