-Both is about a love story between a korean man and a japanese woman, and the subsequent cultural clash between korean and japanese culture

-Both have an attractive korean male lead: T.O.P. in TSM and Won Bin in F2002
-Both are short: TSM is 18 eps x 15 min and F2002 is 4 eps x 50 min

DIFFERENCES:
-TSM is more artful/deeper meaning and has the better stunning cinematogtaphy and a more darker and mystical tone
-F2002 focuses more on the cultural difference, while TSM more on past hurts and love itself
-TSM is better than F2002

ALSO, Check out:
-Ueno Juri's AMAZING acting in TSM!
-Yoo In Na (Goblin, Queen In Hyun's Man) as side character in TSM
-Lee Dong Gun supporting role in F2002

-Both REVENGE ROMANCE MELODRAMAS, where male lead takes revenge on family (direct family & family-in-law respectively)

- Both have a leading male actor whose acting is AMAZING! (Green Rose: Go Soo. ISILY: So Ji Sub)

-I'm Sorry I Love You is better (10/10!) , so it's better to watch Green Rose first, other way around may feel like a step-down, especially GR male lead's trauma might seem very light in comparison to the trauma of ISILY male lead's.

-ISILY has a more sympathetic/tragic male lead than GR
-ISILY is more romance-focused & the love story MUCH better
-GR is slow-paced, while ISILY has a much better pace/doesn't drag or bore you

Both deal with Life/Death.

My Fantastic Funeral is about a dying-of-a-disease girl planning her own funeral who falls in love

Loss:Time:Life is weirder, with people having additional time after their deaths to make up for what they'd missed before they really die. No love story in LTL.

Both tackle deep Life/Death questions.

This is the korean remake version of the original Loss:Time:Life japanese drama.

Both deal with deep Life/Death questions.

Goblin is a drama with same leads/chars throughout all episodes like it usually is, while Loss:Time:Life features different characters per each episode / is an anthology series

Goblin also has romance, LTL only deals with the life/death part

-Both Heart-breaking ROMANCE MELODRAMAS, with leads that are perfect together/GREAT CHEMISTRY & Cast /can act

-Both are great dramas, but ISILY is better (10/10!)

DIFFERENCES:
-REVENGE element in ISILY, no such in LITFC
- ISILY is a korean drama, while LITFC is a chinese drama (that reminds me more of a kdrama, a cdrama for those who don't like cdramas. Also NO dubbing over their real voices in this cdrama!)

-Both ROMANCE MELODRAMAS by the same writer with EXCELLENT leads that are perfect together, GREAT CHEMISTRY and can act (Go Soo + Han Ye Seul & So Ji Sub + Im Soo Jung !)

-Both have strong/likeable female leads who are annoying at the beginning since they have a 2nd lead/male, but grows lovable

-Allthough both dramas are good, ISILY is better (10/10!)

DIFFERENCES:
-ISILY has a REVENGE element, no such in WISFC
-ISILY is MUCH more heart-breaking, especially the tragic childhood/background story of the male lead

-Both are very angst and tear-filled ROMANCE MELODRAMAS where leads know each other for years, and struggle to overcome obstacles in order to be together
-Both feature a class difference between leads
-Both have EXCELLENT CASTING & LEAD'S CHEMISTRY and they can act too. Casting for other characters is great too (Shout out to JO MIN SOO who plays male lead's mum in WISFC, AMAZING actress!!)
-Same structure: Both love stories start out in unsatisfying way/too fast/unbelievable. DON'T be discouraged by the starts of the loves, it gets REALLY shippable/more believable later on & they have EXCELLENT chemistry. Both have an ambiguous/mini ending type of episode some eps before ending that can be seen as ending if not satisfied with real ending (ep 11/16 of WISFC and ep 16/20 of LITFC)
-Both have strong female leads

-Both very underrated dramas
-Both are very sad/emotional, and thus only recommended to those who love sad stories (NOT for everybody!)

-Both have GREAT OSTs, that supports love story really well / makes you ship them more!

DIFFERENCES:
-WISFC is a korean drama, while LITFC is a chinese drama (which reminds me more of a kdrama! A cdrama for those who normally don't like cdrama. Also NO dubbing over their real voices in this cdrama!)

-Both are about an immortal female lead who falls in love with a mortal/human male lead
-Both are short: LFATM is 10 eps x 20 min, SITYO is 5 eps x 10 min.

Differences:
-LFATM has the added element of love counseling (female lead is a love counselor) & Music element (male lead is a rapper/singer)

-Similar kind of female lead, both sassy, colorful personality and both are some type of counselor (Love counselor in LoveAThousandMore and Psychic counselor in Madame Antoine)
-So both are about a female counselor who falls in love, concidentally both fall for their neighbor who they find irritating at the start
-Leads who are cynical about love, in LFATM it's the female lead that's cynical, in MA it's male lead
-Both have a good flow/ not too slow-paced/ keeps you hooked, not bored
-No irritating side characters, you care about the side characters stories as well /they're likable

Differences:
-The supernatural element in LFATM (female lead is immortal) is missing in MA. .....A.K.A love counselor uses her long immortal life in guiding others and is really immortal , psychic counselour is not really psychic but uses trickery to help others
-Psycholigical experiment and mental patients included in MA, none of it in LFATM
-Music element in LFATM (Male lead is a rapper/singer), no such thing in MA
-LFATM is 10 eps x 20 min webdrama, while MA is 16 eps x 1h full drama
