Those series are of different genre completely, so proceed with caution.
Similarities - in both series one of LMs - a young boy, lacking mother figure (Papa & Daddy) or missing his mom - you can imagine level of cuteness and situations.
Then, there are big differences - Papa & Daddy - lgbtqi series, like exploration of daily challenges of gay couples, Light on My Lion - it is more a thriller and found family, yes - with male family members only, and nothing else.

Japan just did it again, killing us by kawai level of level - infinity! Actually, havent seen such series from other countries?
Both dramas are centered around 5-6 yo male leads, both - escaped from parents in one way or another. So, as can be expected, they bear some trauma and act like adults in some situations. Still, both series are cute, with some detective plots, but mostly - hilarious daily situations

Japan recently introduced a lot of series around male families only, be it 1 or 2 generations, not bl - just ordinary single parent/sibling.
Four brothers - speaks for itself - daily routine and hilarious situations of four brothers, the youngest being 5-7 yo , the eldest - supports family
Lion - similar plot, oldest brother support autistic younger brother, then Lion jumps into their life, destroying order and wreaking cute chaos.

Level of kawai - too high. Both series explore mundane days of families with no mother figure, in both - brothers dedicated themselves to younger siblings upbringing. In both we have young cute boys, hence kawai - you cannot not smile .
Our dining table is more on bl side, though not explicit, Lion is more a thriller , mostly around family.
Just realized, both are japanese,

Similar characters (same names) along the same storyline... Lu Zhi Ling using her wisdom and tenderness as a defensive weapon to protect herself and the future of her unborn child. In the process, she helps Bo Wang find a non-violent path and reconcile with his dark-hearted father.

Feels similar as in-
1. Female lead disguising as a man
2. Fl being a powerful general with military achievements.
3. Fl (sort of) betrayed by someone she trusted
4. Change of identity

While the shows dont seem very similar on the surface, they have the same director. Theres also a couple of scenes in Wandee Goodday, where the characters are watching TV and the show theyre seeing is The Eclipse.

- the shows share the same director
-while there arent many elements that are similar between the two series, both include nc scenes
- theres a small easter egg in wandee goodday: Wandees apartment number is 609.

Both are sequels to gmmtv produced dramas of the same director. They depict messy relationships and drama. Friend Zone also has a gay storyline and Joss in a role.

Both are gmmtv produced thai dramas of the same director. They depict messy relationships and drama. Namtan also has a lead role in both shows and in Friend Zone 2 theres sapphic pairing too.

FC enters a fictional world as a secondary character and tries to survive. She becomes emotionally attached to her new world.

Both are movies set in high school in which the ML is the popular bad boy of the school and the FL has a crush on or is looking for a boyfriend and ends up forming a quirky partnership with the ML that turns into love. Both movies have a similar vibe and last minute happy endings.
