Similarities:
-Both shows deal with school bullying
-Both have a mystery behind student's death/accident
-Both focus on the aftermath of tragedy

Differences:
-Unlike Beautiful World, Solomon's Perjury focuses more on the classmates of the student victim whereas BW focuses on the victim's family and their struggles with the tragedy

-Also, the students in SP attempt to investigate the tragedy through a "school trial" whereas in BW the parents are the ones to investigate their son's accident

both stories are the same "ugly woman finds magical item to be pretty" theme... both posters really look the same too xD and I want to say QOTR had something to do with runways and models too(?)

The Beauty Inside, the drama, is also about Prosopagnosia (face blindness). Anyone who is intrigued by the face blindness aspect of The Secret Life of My Secretary might also appreciate seeing a slightly different take on the disease in The Beauty Inside.

the male lead is both have mystery realted to psycopath tendency.
nice plot. great plot twist.
great team work
veteran actor play in here

fishy, full of mystery, murdering. The way the team work hard to solve case.
everything is made as a puzzle which is really hard to be predicted.
if you like something as thrilling as signal, then this drama must be your first choice.

Veteran actor play in here, with great acting.

The drama focuses on a young college love and their developments. It’s sweet and from the same Writer who created A Love So Beautiful.

Both dramas center around a school love transported in adult life. In both series the leads struggle with their daily problems and try to solve it on a daily basis.

Both are noona romances set in the entertainment industry with the love interest as their client. Both dramas focus heavily on life in the industry and the politics inherent in it.

Both are noona romances set in the entertainment industry with the love interest as their client. The main difference is that Top Management's heroine has a supernatural ability and Top Managment is less heavy on the romance.

Same actor. Same comedic/light tone. Both are short, easy entertainment. Puppy Honey has two main storylines with a straight couple featured as well, but if you're not into that it's also easy to skip through and still follow the BL.

(KIND OF A SPOILER BUT NOT REALLY)
- the killer in abyss is reincarnated and continues killing, while in possessed the killer possesses random people and continues the killings

Both are BLs with a light-hearted tone. Love By Chance is less comedic and more serious, but still has its funny moments. Both have lead's who are explicitly gay, rather than 'gay-for-you' and supportive mothers who play a role in the series.

Both are university romantic comedies. The male leads are extremely similar: both have very sweet, nerdy, quiet, cool male leads who unwaveringly love the main lead in a very sweet way although they can be oblivious to the female mind and dating dos and donts (in a very enduring way). The MF is also fun to watch and are both trying to figure out their place in the world. At the end of the day both dramas leave you feeling warm and bubble, although can be easily forgotten.

These two shows are extremely similar to each other in terms of tone despite one being all about female idols and the other having both male and female idols. Both are about chasing your music dreams and wanting to succeed at them. There are dead or dying siblings being replaced, a rivalry between two leads and a focus on trainee competition in both dramas. The only real difference is that My Idol has a very cute romance in it while Idolm@ster is more about friendship.

In both of the dramas the main actors have to live in the same house.
and also in both cases there is a bit of tension between the actors. it is also similiarbecause both has romance and comedy.
Kakafukaka is a bit more mature though.
anyway I think that if you liked one of this dramas you might like the other too!
