Adventure of the Ring

Yi-Zhi's perfect proposal to his girlfriend Lisa is disrupted when he loses the engagement ring on a train.

Zong-Fang lies to win over Ya-Wen's mother, but risks losing the love of his life. After Lisa flees to her parents' house, Yi-Zhi sets out to win both her and the ring back.

The ring ends up in the hands of retiree Yun-Sheng, who bumps into his college sweetheart. Meanwhile, Lisa spends more time with Alan, and Yi-Zhi tries to manage his feelings.

Yun-Sheng and Ching-Fang try to get the ring back when it's taken by a gangster, and Yu-Zhi attempts to be honest with Lisa.

As Lisa moves out, Yi-Zhi gives up on himself, while college student Zi-Long tries to return the ring he's found to his crush Amy.

Yi-Zhi and Lisa become roommates after drama arises between Lisa's parents. Meanwhile, Zi-Long suspects his father of taking the ring.

When she crosses paths with the ring, struggling radio show host Rossy finds herself in a failing marriage. Though he wants to, Yi-Zhi realizes he cannot give Lisa the promise she needs.

As Yi-Zhi and Liza prepare separate trips abroad, Yi-Zhi finally gets the ring back -- and through learning of the ring's adventures, finds the answer he's been searching for.
