Boku Dake no Madonna (2003)

Both tell a story about older woman falling in love with younger guy. AND both drama's have Takizawa Hideaki as main role ;)

Kyoichi Suzuki is an average college student in his junior year. Although he's not in one of the top universities, he's satisfied with his college life studying architecture. Kyoichi left home and is finally on his own, living in a beat-up apartment in Tokyo. However, this apartment building is home to some out-of-the-ordinary residents, who are always bugging Kyoichi. His next-door neighbor hits Kyoichi up for a loan when he finds out that Kyoichi just got paid. His other next-door neighbor who works at a nightclub, always calls Kyoichi, demanding him to come pick her up because she's so drunk. Other than that, Kyoichi is satisfied with his normal life until he meets a girl one day.

Kyoichi comes home from his part-time job as a night-time security guard. He returns to his room to find a girl sleeping on his bed - a girl he has never seen before. She looks a bit older than Kyoichi and is quite beautiful. Kyoichi can't believe his eyes. Kyoichi closes the door and goes outside to the entrance of the apartment, to make sure he's in the right apartment and room. There's no mistake. He returns inside, but the girl is gone. There's nobody in his room. Was it just his imagination? Was he hallucinating? Kyoichi can't understand what just happened.

Later, he discovers that something is missing from his grocery bag - the Chinese noodles he was looking forward to eating are gone. This is how Kyoichi first meets Surumi Kataoka. After they meet, Surumi continues living in Kyoichi's room. She points to an apartment visible from Kyoichi's room and says that the guy living there dumped her for another girl. Surumi says that she's waiting to check out the girl she was dumped for. Kyoichi doesn't know if he ought to believe her or not.

All Kyoichi knows is that while Surumi is such a charming girl, the expression on her face is sad at times. Kyoichi is not that disappointed about sharing his room with a cute girl. He starts to think that this lifestyle may go on forever, until one day, Surumi suddenly disappears-just like the day she suddenly appeared. All she leaves for Kyoichi are unanswered questions.

Tanimachi Mizuho has big dreams of living in Daikanyama and becoming a famous writer. In the middle of the winter, this strong-willed 26-year-old moves to Tokyo from the snowy countryside. Never doubting her ability, she keeps telling herself that if her desire to realize her dreams is strong enough, they will come true. What is waiting for her in Tokyo though, is something altogether different. Morinaga Kenta is an up-and-coming variety program scenario writer. Kenta moved to Tokyo five years ago, and with luck on his side, he became well-known in no time. Kenta and Mizuho are from the same hometown, and were friends growing up, but their friendship never blossomed into anything else. "Hachiko," as Kenta was known as when he was growing up, just goes with the flow and doesn't really have any big aspirations for himself. These two, who aren't having much luck with work or with their love lives, suddenly run into each other one day in Tokyo in the middle of winter. Being 26 is a tough point in life because it's too late to think of new dreams, but on the other hand, it's too late to abandon old ones...

A love story unfolds about 7 people, including Kume Masakazu. They are in their 30's, live in Tokyo, and have their own views on love and friendship. Kume Masakazu is single and 33-years-old. He works as a struggling screenwriter. He doesn't have a girlfriend, because he has decided to cut off contact with a woman after meeting them 3 times. Because of his tendency to run away from love, his friends call him the "Man Without Love."

Both star Takizawa Hideaki and have similar characters and plot devices.

Both stories involve a female lead who spies on a male character from another building and has a mysterious past the male lead is curious about. The neighbors in the building also have a prominent part in the drama like in FBND.
