Short drama where female lead plays a male in order to save her writing career
Good Doctor is another drama that has many situations that can be similar to It's Okay, That's Love. This drama may have episodes that drag, but that may only due to it being a medical drama. A good watch, however.
Although not as deep as It's Okay, That's Love, this drama also touches on mental illnesses with the leading male Seo Jae Hee. I also found myself emotionally invested with the lead and found myself wanting to cry when he did. Again, not as deep but worth the watch
