Cha Jung Han is a detective for a special investigation team. He is busy with investigating violent cases including drugs and gangs, but one day he takes in his niece Eun Ae and struggles to raise her.

Han Ye Seul is a single mother who raises her 5-year-old son alone. She is Cha Jung Han’s first love.

The drama draws a love story between two co-workers at an insurance company, with Kim Ji Hoon playing the company's smart-as-a-whip lawyer. Because he carries the hurt of having been abandoned by his birth mother, he doesn't easily open his heart to others. Jin Pal Kang is a 25-year-old employee of the company who becomes responsible for her five younger adopted siblings after her parents meet with sudden deaths

Three young men—Dong Gu, an unlucky aspiring film director; Jun Gi, an eccentric actor; and Du Sik, a lazy freelance writer—open a guesthouse called “Waikiki” in Itaewon to fund their film. Despite their lack of experience, they dive into the challenge.

They are joined by Dong Gu’s practical sister Seo Jin, single mother Yun A with her mysterious baby, and Dong Gu’s ex-girlfriend Su A, creating a chaotic and uneasy household.

Both couples have an early connection (one night stand in car, sleeping in same bed) and in both struggle with their own problems before finally reuniting as a couple.

Complicated family past, trauma, 2ML and 2FL both have one sided crushes on the leads.

Both dramas have ML character abandoned by their siblings and forced to take good care of their nephew, and FL characters' conflict with theur family.

However in the Spring Fever, the nephew is no longer a baby but a teenager, and instead of being orphanized, the nephew was abandoned by his living single mother (ML''s sister). However, everytime seeing Our Universe, it reminds me of Spring Fever's ML when his nephew was a baby and he was forced to take good care of his nephew, and even in SF the ML must take good care of his nephew alone.

Making Family is Korea- China collaboration about a Korean single mom and her kid conceived by artificial dissemination.
But the kid wants to know his biological father and discovers his biological dad in China and ... goes to meet him. The kid eventually wants his mom to get together witih that man.

Making Family is a very functional, warm family drama with a cute kid.

As manager of a dessert shop, Cheng Mu has only one desire: to make his shop the best in the business. Working hard to make that dream come true, Cheng Mu is overjoyed when his shop begins to grow in popularity. But with that popularity comes the attention of those he would rather avoid, namely snobby food bloggers who think more of themselves than the food they’re reviewing. Among the most popular food bloggers is Jiang Si Han, a wealthy food blogger with a dedicated following. Following the rumors surrounding Cheng Mu’s shop, Si Han arrives to find out for herself what all of the fuss is about. Skeptical at first, Cheng Mu’s delicious desserts eventually win Si Han over. Of course, having a kid as cute as Rui Rui around to tear down Si Han’s defenses only made winning her over that much easier. Finding herself returning to Cheng Mu’s shop more and more frequently, Si Han can’t deny the feelings that stir, every time she’s there. With a heart growing more fond of Cheng Mu and Rui Rui by the day, will Si Han find her life taking a rather unexpected turn?

Familyhood is about a very jerky woman who wants to improve her image by having a baby, so she hires a pregnant teenager and plans to snag the baby, claiming it is hers. However, the plan backfires.

Just like in Our Universe, where ML went from a jerk to a caring dad and FL went from a clueless moron to more caring, the Familyhood FL and the teenage mom become good co-parents to the kid.

Two single fathers get together to raise kids left by terrible mothers.
One of the kids is a left by a stranger woman

The similarity: Two unexpected people raise a child together.
