Yoo Yeonseok, Kim Kyungnam, Esom Love Triangle

In the 11th episode of SBS's Friday-Saturday drama 'Woo, Also Law Firm,' the 'Okcheon Building Four' mobilized to resolve the inheritance case of shoe craftsman Kang Dong-sik (played by Lee Deok-hwa). Kang Dong-sik left a will bequeathing one-third of his assets to Cha Eun-seong (played by Ra Kyung-min), the son of his former co-founder Ryeo Seon-hwa (played by Bae Yeo-ul). Consequently, his biological son Kang Ji-hoon (played by Byun Jun-ho) filed a lawsuit, refusing to acknowledge the will. Meanwhile, his wife Chae Jeong-hee (played by Gil Hae-yeon) opposed this by entrusting the case to Shin Irang (played by Yoo Yeon-seok) to uphold her husband's final wishes.

During the trial, Yang Do-gyeong (played by Kim Kyung-nam) from Taebaek Law Firm raised suspicions of will forgery based on ink acidity and handwriting analysis data, pressuring Shin Irang and Han Na-hyun (played by Esom). Furthermore, the case faced the brink of defeat when it was revealed that Chae Jeong-hee had previously reported Ryeo Seon-hwa as a spy.

At this moment, the possibility that Ryeo Seon-hwa, who was presumed dead, might be alive was raised. Shin Irang received a note believed to be written by Ryeo Seon-hwa, and Han Na-hyun proposed a negotiation to Yang Do-gyeong. Yang Do-gyeong warned Han Na-hyun, "Shin Irang is dangerous," but Han Na-hyun retorted, "I like that he's different from me," creating a subtle atmosphere. Unconsciously, Yang Do-gyeong asked, "Then what about me?" revealing his unrequited love for Han Na-hyun.

Han Na-hyun initiated the 'Search for Ryeo Seon-hwa' by proposing a preliminary injunction for profit distribution with Ryeo Seon-hwa's son as the plaintiff. Eventually, Ryeo Seon-hwa's identity was revealed to be the owner of a nearby noodle shop. Through Kang Dong-sik's earnest efforts, a dramatic reunion between Chae Jeong-hee and Ryeo Seon-hwa was achieved. Ryeo Seon-hwa told Chae Jeong-hee, "Even if it wasn't for you, Jeong-hee, I was destined to be caught," easing Chae Jeong-hee's guilt. With the misunderstanding resolved, Kang Ji-hoon withdrew the lawsuit, and the case concluded with reconciliation with Cha Eun-seong.

After resolving the case, Shin Irang decided to convey his true feelings to Han Na-hyun, announcing his confession by saying, "I won't regret it. I'm going to say it now, my feelings." However, just before the confession, Shin Irang suddenly experienced an unprecedented event where he became possessed by a dog, leaving Han Na-hyun bewildered. This unexpected ending left viewers with both laughter and a sense of regret.
