The female and male lead from Weightlifting Fairy both appear as supporting roles in Cheese in the Trap so if you love this actor and actress make sure to watch. I think that Lee Sung Kyung does a great job acting in both roles and it after having seen her in Cheese in the Trap and then seeing her in Weightlifting Fairy I think she is a top rate actress and I really loved her roles. She was over the top crazy in Cheese in the Trap as In Ha and she is a spunky strong girl as a female lead. Both have great story lines with strong female leads for some girl power and attractive hot male leads.
If you loved Strong Woman Do Bong Soon I would recommend Weightlifting Fairy Kim Bok Joo as they both feature spunky and actually physically strong girls who both get into a lot of troublesome situations with great comedy ensuing from that. Both girls are also strong female leads in that they are take charge kind of gals and both want to be seen as girls and not just for their physical strength . The romances in both shows develop slowly and they are great rom coms and very fun to watch.
If you liked Heartstrings try Trot Lovers, they both feature a pop singer male lead paired with a traditional music girl and they both have really good ost musical scores that are catchy and will get you wanting to sing along with them. They also both have really good and quirky side character relationships.
