Orphan of a wrestling legend....
Dojo threathen to buy by a rich rival dojo / gym...

not dorama but anime - Sekai de Ichiban Tsuyoku Naritai!
very similar in many ways.....
While Tofu Wrestling is idol highschool girls wrestles part time....
In Sekai de Ichiban Tsuyoku Naritai!, idol goes into wrestling after witnessing her friend being beat by a pro wrestler....

lead cast in Sekai de Ichiban Tsuyoku Naritai! - SAKURA
lead cast in Tofu Wrestling - SAKURA
both wears red & white wrestling gears
both faught to reach the top (finals)
both are short black hair (In the anime Sekai de Ichiban Tsuyoku Naritai! Sakura cutted her hair in the middle of the series)

Very very similar, in terms of main cast, costume, plot, even setting, etc.
let's just say its a new Shomuni (5). While Shomuni 4 is a sequel of the past dramas (similar title), Age Harrasment is a another alternate ver. of the franchise.

Both have plot focusing on the gap between the high society (rich) vs. the poor.

Very similar theme....
1. focusing on a promising highschool girl turned hostess

2. then being bullied jealous by colleagues

3. little by little gains respect from customers, her boss, and colleagues becoming a star in her workplace.

4. main protagonist turns out to be the savior of the club (in various situations) she is working at.

on the flipside.....

1. Jyouou Virgin have AV idols as casts thus the exposing of nude scenes is a plus while Jotei is somewhat on the conservative side (no av idols).

2. Jyouou Virgin focuses on a highschool girl who wants to be love and accepted in society joins a competition of cabaret girls gathered around Japan in run for the prize money, while Jotei focuses on highschool girl who decided to be a Jotei (Empress) - top cabaret sort of legendary title, in order to take revenge to the people who have money and power who steps on the poor for fun.
