Both MLs are rich and either disabled or ill, FLs have secret motives and pretend to be mentally disabled.

Both FLs pretend to be mentally disabled/ill in order to achieve their goals, both MLs are wealthy men who take them in, unaware of their motives.

Both are short length dramas in which the ML keeps and torments the FL, blaming her for the death of his family member. She eventually becomes pregnant and tries to protect herself and the child against the evil people around her.

Male lead in both dramas are extremely smart and both shows are just full of surprising and shocking events. It's just that Joy Of Life has more comic and funny scenes where as Nirvana In Fire has a very serious and tight plot. If you wanna watch a perfect drama with almost no flaw regarding costume,set up,story or anything NIF is the defination of perfection. JOL might not be that perfect and accurate in terms of costumes and the seriousness but I must say both dramas are equally important to me and if you are really into c-dramas looking for something really good please please do miss any of these. The most important thing about both the dramas is that they have got the best actors of the industry and I mean it. It will not disappoint you.

both are Korean GL released by SUKFILM on their youtube channel !! i recommend both of them if you like short, well-writed web series :)

they both have the same production studio (SUKFILM on youtube), one is a GL while the other one is a BL, but i promise they both have great chemistry, acting and storyline !!
