Papa & Daddy (2021)

Similar in aspect of it concerning two fathers raising their child while struggling with the heteronormative society and how to explain to their child their difference from other families but still normal, while others try to tell them otherwise.

Same premise of gay couple who have a child and their struggles in both exploring how to explain their unique family to their child and their child's exprience at school.

Same themed : 2 dads & a child...both are sweet and a bit lovey-dovey too.

They are both about two fathers who look after their young child as they start going to school.
Both families were judged by outsiders due to their unique family situations.
P&D is LGBTQ+ while Two Fathers is not
Wholesome family Taiwanese show
All 4 fathers are nice and kind-hearted

A same sex couple raising a child and having to deal with the difficulties and the judgement from it.

Both are taiwanese lgbt projects that follow a gay couple with an age gap. Theres affectionate scenes. The Immeasurable is alot more dramatic though while Papa and Daddys lighthearted and more focused on lgbt topics.

not much to say tbh ,, both focus on a family with members of the lgbtq (i dont know how to phrase it) . papa n daddy is overall a lot more light-hearted

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.

Overall both shows are different in plot, but they both feature a friendship group that are all LGBTQ+ members/allies.

Both shows also focus on the more realistic issues that gay men face, though P&D is more focussed on parenting while HO has more to do with friendships and love.
