Papa & Daddy

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.

season 2 continues the story
.........................................................................

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 slice of life BL dramas centered around food and one of the ML's families coming to terms with his sexuality. Both have a similar warm but very realistic and sometimes poignant vibe.

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.

Saionji, a housework-application employee who doesn't do housework, is enjoying the freedom of single life she's finally obtained after 38 years! However, she meets Kusumi, a genius engineer from Silicon Valley. The strange younger man has a big "secret"! This is a story of love and family, where Saionji-san, who has no housekeeping skills, takes on the challenge

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.

Mi Yeon is an independent career woman and a documentary producer who became a widow after her husband died in a car accident over nine years ago. Despite that, she dreamt of having her own family so with the help of a sperm donation she gave birth to a boy. After her son turned nine years old, he set off to go to China in search for his biological father. Mi Yeon also went after him, and together they met the boy's father, Zhou Li Yan. The three of them go through some unexpected situations and become a family.

Even in modern-day Taipei, women feel the societal pressure to get married and have children before the period to have them. Thankfully, there is a solution: freeze your ovum and prolong your fertility. Zeng Mei Bao freezes her ovum and looks for the right man to start a family. In the pursuit of this man, she ends up in a wintry Swedish Province, where ice and snow becomes a metaphor for the unborn child who is waiting to be born

Similar to both season one and two of Papa & Daddy (and also from Taiwan) with taking care of a child, though Papa & Daddy it's an established couple.
