based on stuff i've read

Adapted from the manga with the same title by Mizuta Yuki 

heavy changes to the plot - the story is messed up in itself but personally i cannot recommend the drama and will always chose the manga over it - the changes ruined the story for me

 Adapted from the manga "Love Stage!!" (ラブ ステージ) written by Eiki Eiki (影木栄貴) and illustrated by Zao Taishi (蔵王大志) 

also includes more of the parent story "back stage!!"

multiple changes to scenes and some has been exculded - but the overall story is the same

 Adapted from the manga "Love Stage!!" (ラブ ステージ) written by Eiki Eiki (影木栄貴) and illustrated by Zao Taishi (蔵王大志)

Adapted from the web novel "Semantic Error" (시맨틱 에러) by Jeo Soo Ri (저수리) 

the original story is still ongoing so the story had to be shortened which makes it feel rushed towards the end - the sexual plot has been removed and some small changes to the scenes

Adapted from the webtoon "Cherry Blossoms After Winter" (겨울 지나 벚꽃) by Bam Woo (밤우)

Adapted from the webtoon “Oh! My Assistant” (오나의어시님) by Mila (밀라) and Angrymonster (앵몬) 

the webtoon has a strong sexual focus which had to be censored for the drama. (reviews state that that hinders the story majorly - take that as you want)

 Adapted from the manga series  "Ameiro Paradox" (飴色パラドックス) by Natsume Isaku (夏目イサク)

Adapted from the web novel "The New Employee" (신입사원) by Moscareto (모스카레토) 

the drama removed the sexual plot parts - i do not like this drama, the plot changes are not apprechiated on my side but my main problem is just that the main character comes across totally different in the drama (webtoon: reliable, talented, doesn't let himself be screwed over; drama: just a baby)

Adapted from the manhwa "A Shoulder to Cry On" (소년을 위로해줘) by Dong Mul (동물) 

some smaller detail changes but noting noticably different

Adapted from the manga "Bokura no Shokutaku" (僕らの食卓) by Mita Ori (三田織) 

adaptation is one on one

Adapted from the manga "Taikan Yohou" (体感予報) by Taino Nikke (鯛野ニッケ) | eng title: My Personal Weatherman

adaptation is pretty one on one with small changes

Adapted from the manga "One Room Angel" (ワンルームエンジェル) by Harada (はらだ)

Adapted from the webtoon "The Ideal Relationship" (호형호제) written by Ken (켄) and illustrated by Nod
