In both:
(1) archery plays a major role
(2) the main characters are in school
(3) romance & competition are significant for plot development
(4) their social lives are rooted within their respective teams
(5) an ancillary, but important, character is hospitalized
(6).G-rating

In contrast:
(1) BtK, (Japanese movie) the FL is the primary archer
(2) BoYimM (Chinese drama) the ML is the focal archer.

SAME = both have leads with multiple personalities, hypnosis is included along with ambiguous relationships with their psychologists

DIFFER =
KMHM: ML has several personalities and FL is mental support, romance is more
evident
SdKdSdPwW: FL has 3 personalities and a twin is involved while the ML is
emotional support, murder investigation and an aspirational hero are
more central

in a nutshell: Good looking men with feline characteristics

how are they different?
-drama vs. webtoon,
-length which translates to character development
-episodic as opposed to MLP with one unifying plot and fuller story
-appearance of cat characteristics...in MLP they only appear when the ML is emotionally agitated, they dissipate when he is happy

Both FL are workaholic manga writers who are being challenged to be open to love by editors.

MOL has more situational awkwardness and stock characters rather than actual storyline while Sensei has deeper character development (obviously time length difference is part of this).

In both Taiwanese dramas, the FL serves as a bodyguard. Each is a motherless children who has been heavily influenced by her fathers whose occupation is in a male-dominated world. Both FLs have supporting male friends who follow their fathers' orders and help them run interference as needed.

Differences
(1) FL context: TP involves a triad (I know obvious given the title) while SSB uses a security company lead by a former military man.
(2) FL role in love triangle: SSB has a clear 'nemesis' vying for the ML affection (2 females and 1 male) while TP has 2 men competing for her (2 males and 1 female)
(3) ML context: ML for TP is in show business while SSB ML is an automobile dealership CEO
(4) type of romantic story: SSB is more melodrama with lots of character development while TP is glitzy idol fare
(5) series length: TP = 6 30-40 minute episodes, SSB = 82 45-minute episodes

FL = spunky, hard-working, lower income with a very sophisticated palate
ML = wealthy, award-winning chef with cold exterior
context = decadent and delicious food!!!! lots of flashbacks

differences: much more manipulative scheming in DD and quirky musical number in TPM

MLs = bossy, neurotic, allergy-ridden artists who are difficult to please and find it nearly impossible to trust others. Both have tragic family backstories that involve abandonment

2MLs = incredibly adorable and good-hearted, connected with ML but have history of not getting along

FLs = thrust into a high-art context they are not used to and stumble through to navigate that world and make it their own

differences = fantasy element in Perfume, Kpop/music in Full House Take II

Both involve students finding love/romance in a virtual world; both feature a ML who is highly ranked (Unexpected = creator of universe; Love O2O = incredibly highly ranked fighter;, both have good, hard-working FLs who are envied and castigated by other females.

Of course personalities, IQ levels and the struggles outside the relationship are completely different. And Unexpected is fantasy where everything occurs in an alternative reality while Love O2O resides firmly in a reality that would actually occur in the present- the moments within the game are always clearly contextualized as part of the game--not reality.

I enjoyed both. The fantastical elements of Unexpected make it a lighter story but both are worth watching.

Both involve

(1) quirky, clever female leads with an artistic bent andmartial arts skills (which mysteriously come and go depending on the context) who end up helping a male idol (or two). Both leads struggle with how to manage rabid fans while being in the idol's "real world."
(2) self-aggrandizing male leads who have far too high an opinion of themselves along with some sort of daddy issues

While Accidentally in Love doesn't require co-habitation and moves a great deal of the movie to a university, the overall dynamics between the leads are similar.

Both shows are set within the telecommunications industry and explore ethical questions around news delivery. Both have spunky female leads who are passionate about reporting.
