Kimi wa Petto (2003)

Both drama serve as the female lead's "dog."

Kono Otoko is more of a comedy while Kimi wa Petto is surprisingly grounded.

KWP doesn’t have explicit BDSM the way Love and Leashes does, but the aspect of dog role play and the relationship between the fl and ml is definitely a DS one. Both also delve into how engaging in DS helps relieve stress and anxiety for both parties in different ways.

After learning that his ex-girlfriend has a fabulous new boyfriend, Hyun Seung spends his nights wracked with insomnia and jealousy. Then one night, a phone call from a sexy stranger breathes new life into his gray existence. Even with her enviable looks and a successful boyfriend, Yun Jung feels love deprived. While attempting to spice up her relationship, Yun Jung resorts to giving her boyfriend a steamy phone call… only to find that the guy on the other end is someone else and she just can’t quit him!

Kimi wa Petto is about a woman letting a man live in her apartment on the condition that he behaves like a dog at home.
My Woofy Poofy Love is about a woman co-habiting with a man who can actually transform into a dog.

When her boyfriend was caught cheating on her, Terada Aki moved out of her apartment and into a sharehouse, where she found herself reunited with her first love, Hongyo Tomoya. Hongyo is novelist, but he has recently been having trouble with his writing, and he asked Terada for help - with a shocking proposal. To complicate matters, the other residents in the sharehouse also start interfering in Terada's life.

Both plots are about an older woman and younger guy who is kinda obedient to her thus called her "pet"...

Both dramas are sweet and about two totally different people developing feelings for each other as they learn to depend on the other while living together, although Kimi wa petto is a bit more extreme with the conditions for tenancy ;)

Maria, struggling financially, juggles a low-paying day job with nighttime shifts at a cabaret to fund her sister Nana's eye operation. Tragedy struck their family when a young Maria accidentally caused a fire, resulting in Nana's blindness and their father's death. Shiro, a discontented concert pianist, crosses paths with Maria in a traffic accident, leading to his hospitalization. Adopting a false identity and amnesia, Shiro seeks refuge at Maria's home, eventually becoming a cabaret pianist. Unbeknownst to them, fate weaves a complex web, revealing that their lives were never meant to intersect.

Follows the same plot but more heartwarming and more importantly(for me) full of Matsujun :)

Older Successful Woman, Younger less successful man living in FL's house...Same vibe, same feel...just less romantic excitement from Dame na Watashi ni Koishite Kudasai.
