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

Underdog, not so good looking guys with little experience of relationships, going after a woman who would be considered out of their league.

it's the drama version, with the first ending , seeing has this one is an alternate ending.

Similar tale of an Otaku who struggles in life and love, having low self-esteem due to their geeky appearance, social anxiety and awkwardness in having normal conversations.

While Kuragehime is about female Otaku who falls for a guy that is out of her league, Densha Otoko is about male Otaku who falls for a girl that is out of his league.

we all like a nerd underdog love story. but this one doesn't have the internet.

Remake of 2005 Japanese movie Densha Otoko. A must watch both drama & movie. A love story between younger man & older woman who meet in the train.

Both have this otaku-culturish thing with otaku characters solving their problems...

Both dramas have the "loser" male lead/successful female lead trope.

Similar story of male lead who's never been in a relationship finally get into one and discovers it's not all fun and games.

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.

Many similarities in the plot including a main character who idolizes a female lead who's out of his league.

Similar premise of an inexperienced guy falling in love with a beautiful woman who is completely out of his league, as he get his first taste of love and heartbreaks.

Although Densha Otoko is more comedic, Takane no Hana is more serious, due to the overall plot of her family's story of succession and inheritance.

Both feature a rich / popular girl and unpopular unattractive guy, and both have a up beat happy ending.
