Begin Again (2020)

Both dramas have a similar way of keeping you guessing on who the female lead will wind up with in the end. I think Reply 1997 does it better though.

I won't say both dramas are similar bcoz this is more on comedy side. This is "an intriguing story" of finding the real dad.

I was able to relate Noh Ae Jung as a mother with female lead in Angry mom. Both of them try their best to protect their children as single mothers and raise them without any need of paternal love. If you liked this drama because of the mother and daughter relationship then Angry Mom is the best choice to watch next. Hope this is useful :)

Reply 1994 was one of Son Ho Jun's first roles. The scenes of his character, Dae Oh, during college in "Was It Love?" really reminded of Reply 1994. Other than that, both dramas use a similar guessing game though Reply 1994 does it better.

Similar suspense to who is the real ML, multiple love interest between the MLs.
You will be unable to guess and the story reveals towards the end.

Same FL actress. Also about romance. Emergency Couple doesn’t have a child. They both have drama about what happened in the past.

In both dramas, the female lead is surrounded by more than one guy who is attracted to her. Both female leads are career women and both have at one point decided not to pursue romantic relationships. Also, the single mom theme is also significant in both dramas.

Go Back Couple has the same male lead. Also, it's another more mature romance. Deals with similar mishaps due to miscommunication between the leads.

Just like in Was It Love, in Woori the Virgin, the mother just made her daughter believe that her father is dead. The daughter grows up with her mom and grandmother. Once the father found out about having a daughter, the father tries to get closer to her, but it's not as simple as we often think it would be. What I had wanted to see more in Was It Love? I can watch here in Woori the Virgin: the father is given a chance to be with his daughter to get to know her better and to be good to her, even without having to hear her call him "Dad".

Both of these dramas have a single mother that meet men
For baek hee has returned 3 men and they are more interested in knowing who the father is and if it's one of them pluse they are mostly talking to the daughter
For was is love as it seems there are 4 men and they are more interested in the main character
Both dramas the boys are trying to be with her or at least try to lastly in both dramas the men have different personalities

both had the "4-against-1 romance" while Was It Love is 4 guys 1 girl and Ex-Girlfri1end Club was 4 girls and 1 guy. plus both have Song Ji Hyo

As principais são mães solteiras que trabalham para criar seus filhos e abdicam de uma vida amorosa em prol disso.
