Both female leads end up an evil extra in the stories they fell into.
Both dramas make fun of common drama tropes and are hilarious to watch.
Plus Tiger and Rose had this one line that can help calm everyone who suffered from Second Male Lead Syndrome in Lost Romance:
"The male lead belongs to the female lead. The second male lead belongs to everyone (audience)."

While Xiao En did not write the novel she ended up in (and hence does not know how it will end), Xiaoqian in Tiger and Rose falls into a drama script she wrote herself, which means her take on how to change her fate would take a different turn than Lost Romance.

Without spoiling the ending -- watch until the end, you'll find parallels in how the male leads are set up too XD

Both works make fun about the current drama tropes and are extra meta to watch.
There's also a blend of the fictional and the real worlds in both dramas -- one character in Be Melodramatic is a drama scriptwriter and it's clear her drama is loosely based on her own story.

Female lead finds herself an extra in a fictional world and fights to become the female lead of her own story.
They also make fun of a lot of drama tropes so the comedic factor is high.

they both have people with a dream struggling to reach their goals and dreams
i think they have a similar vibe even though they have different plots all together.

Both are also controlling.
TLTSILY is more romantic love story with great chemistry while MHTT is more of the obsession to keep the FL

LNF is a lot tamer than MHTT but I get the similar vibes of ML showing their dangerous sides.
There’s also manipulation, jelousy and a bit controlling in LNF but not to the extreme extent as MHTT

They both have a similar idea of assistants pretending to be their bosses. Except that "Fai Gam Prae" is more of a drama with a touch of dark comedy, while "Fun Fueng" is more of a romcom
