전체 에피소드

아이코와 카이는 각자의 반려견을 산책시키던 중 목줄이 엉켜버리는 소동을 겪는다. 반려견들이 첫눈에 반한 거라며 너스레를 떠는 카이에게 아이코는 사랑 따위는 착각일 뿐이라고 쿨하게 받아친다. 한편, 한국 재벌 ‘우로아 그룹’의 3세 서하는 수상쩍은 목적을 품고 조용히 일본 땅을 밟는다.

Seo-ha claims Kai's dog is his, and Aiko, as a lawyer, tries to find a legal way for Kai to keep the dog. To gain her trust, Seo-ha takes Aiko on a date in Yokohama.

Kai's dog is suddenly kidnapped. He suspects Seo-ha, who denies any involvement. Aiko reveals to Kai that they share a past connection involving a stray dog from their childhood.

Kai reluctantly agrees to live with Seo-ha. At work, Aiko finds herself in a difficult position, forced to legally oppose Kai over the ownership of his dog due to her boss's decision.

An old friend returns with a shocking offer for Kai, bringing back a dark past. Tasked to investigate Seo-ha, Aiko instead learns Kai's secrets.

Aiko's confession leaves Kai confused. A new rival emerges as Seo-ha’s sister arrives, confesses to Kai, and vets Seo-ha for the family succession.

Aiko is bewildered after Seo-ha confesses his feelings for her. Aiko's mother, who is consulting her about a divorce, invites both Kai and Seo-ha to dinner, leading to a tense meal.

After Aiko's impulsive kiss with Kai, things are awkward. Seo-ha selflessly pushes them closer. As they finally discuss the kiss, a crisis hits Kai.

Guilt-ridden over Kai's crisis, Seo-ha flees to Korea and rejects their pleas. Aiko's subsequent attempt to uncover the truth backfires, putting her own career in jeopardy.

Seo-ha returns with evidence, uniting the trio for a final battle. As he plans to propose to Aiko, Kai makes the heartbreaking choice to support his friend over his own feelings.
