Train Man: Densha Otoko (2005)

Both of these movies have fresh, funny and youthful writing and characters that give you a sneak peek into a very specific niche of nerd-dom. :) Both movies are quirky and fun but have positive, warm messages overall.

ML is popular & caring person, many girls like him in high school. FL is shy & awkward person. Recently FL is broken heart & ML suddenly hear all her complain about why she's broken heart & why the guy she like rejected her. ML decided to play one side love game with FL but FL can't fall in love with him

Both films are about Japanese ‘geek’ and his borderline obsessive/compulsive hobbies. The Mamiya Brothers are nerds, The male lead from "Train Man" is an otaku.

Set in Nagoya Station, it depicts the encounters of young people who work late at night and what happens after that.

Another special. This one is another special.

Similar love story. Younger man fell in love with older woman. This movie stars Yamada Takayuki & Nakatani Miki.

In both dramas the main characters look to an online community to help them with a problem that they are facing.

Fifteen-year-old Sei Saotome is the type of person who tends to fail at the most crucial times. After nearly becoming a high school drop-out, she enrolls into a school that is overambitious for her. There she meets the bold and popular Taiyou Udagawa; and the dreamy and stars obsessed, Mizuki Ootaka. After being asked by Mizuki to join the two guys in the Astronomy Club, it turns out high school life isn't as bad as she had expected.

Both are about good guys that save a girl from an attacker, and then the quest for love begins! You want to root for both Train Man and Takeo.
