Both drama have sombre tones.... the subtlety, the vibes and the feels are very similar....
Both dramas have FLs who feel too much... then internalise their pain while outwardly they remain cold... the acting in both dramas makes them a treat to watch.... the trunk has more mature scenes though...

Similar chemistry between leads with the additional workplace vibes.... the outsider in addition also involves family dynamics whereas fake it till you make it is slice of life drama with one of the best chemistry between the leads ever seen in cdrama world....

Similar workplace vibes with an unforgiving, strict superior...... both dramas portray great character development and amazing acting.... both dramas are best suited for mature audiences who prefer more substance than fluff....

Similar in the aspect... Both FL get cheated on by their husbands and the story follows their growth from a homemaker to career oriented woman.... balancing work and home life as perfectly as possible.... Dr. Cha is more quirky with heartbreaking and comedy scenes mixed in between... while Alliance has more serious tones...

Similarities lie in the office setting and the constant support of the MLs for their FLs.... Both have green flag MLs... with younger man/older woman trope....

Green flag ML in both who are genius in their fields and younger than the FL... FL in SAHPH is more classy while in RIABB FL is more of a quirky gal....

Both dramas similar in the aspect that... FL raises a kid not their own and get misunderstood by the ML and their family... they undergo lots of trials during the process....

Similar premise...
Lost is tad more mature and way more emotional than one spring night.... the feeling and the emotions they provoke are kind of same though Lost has some scenes where you won't be able to stop your tears.... I would totally recommend watching both of them...

Though both are two different genres…. The feels are the same with similar small town setting and psychological suspense. Hometown is a psychological thriller based on a cult involving mass brainwashing and killing while Monstrous is a horror suspense with an evil spirit that turns humans into monsters by affecting their minds…

Both the dramas depict FL who are misunderstood celebrities and deal with loneliness and negativity from their fans/haters. Both have cute romance. Apart from that both the dramas have different settings. The ML in The Beauty Inside is a rich chaebol suffering from prosopagnosia while in Fanletter, Please ML is a lawyer who has a sick daughter.

Similarities- One of the leads are cursed in both. In TBI the FL while in DWY it’s the ML. The ML in both dramas have similar characters… Being tall handsome and cold which changes when they meet the quirky FL. Overall the feel of both dramas are also similar with sweet romance and quirky comedy in between.

Both dramas involve people with superpowers living on the run or hiding. In both there are organizations who are after the leads.
Apart from that the thriller and gore vibes are kind of similar... although connect is way too much gorier....
Moving has better plot progression and more characters and good character development...
Personally I prefer Moving more...
