Tho it might have some similarities in the plot, those 2 dramas have generally different messages..
But I'm recommending WMLB solely because the melancholic ost reminds me of TTOR's

Boss/secretary relationship ?
Cold/cheerful dynamic ?
Healing component ?
But mostly idk why Joseph Zang visuals remind me of lee Joon hyuk???

office romance with in sync leads..
secretary and boss component is there, ML is taking care of a child, his brother in HWMA, and his daughter in love scout

In fake it til you make it: FL and ML share this businessman, office ppl , very busy sometimes very stressed vibe but they connect because they somehow share close ideals and heal each other .
Tho in love scout ML is not the same kind of busy as the ML in FITYMI (but rather he's represented as hardworking person , loving father and caring person) I believe both dramas will share the same dynamic between ML and FL

Tho meet yourself is set in a village kind of environmental, in both dramas, ML is like a savior to FL . Also in both FL is the busy business woman that is pushed to her limit (in meet yourself it's the death of her bff, in love scout it's her illness)

common: plot is abt reality show about potential of the leads being together
differences: one is abt friends scared of ruining the friendship and the other is about exes scared of getting back together and repeating the past

A second chance to change things in a way
Time travel concept but legally romance happens while she's in a coma
Reconnecting with" the one"plot is there

Same time travel concept same purpose of reconnecting with the one ..
Winter night has a winter vibe and someday or one day felt more in spring/summer

High school sweethearts to lovers in adult life
Difference:
-in wifty it's calmer? FL is energetic and cheerful extrovert but ML is introvert and more mature?
-in love next door I know ML is mature but in FL presence oh he's gonna match her energy alright

Go ahead: siblings to lovers? Nah jk jk "adopted" siblings to best friends to lovers
The bickering, the feistiness is thereee
Love next door: it's like if FL of go ahead ended up with the second "adopted" sibling lol

Betrothed by their families when they were kids, forced to "tolerate" each other in school, developed feelings by the end of it and meet again in university to lovers.
Difference: FL is more feisty in love next door

Childhood friends to lovers...exact same dynamic between the leads!!
Context is different: into the ring the leads meet again in the same work environment (politics oriented)
Love next door focuses more Abt the leads but each their own struggles in work life and personal life but they meet again cz they live in the same neighborhood
