@Dennis thanks, you seem to be describing my lists. Out of the ones you pointed out, I'll definitely watch Marriage Contract because I heard it's good. I actually placed that one on my On-hold list so actually haven't dropped it yet. With One More happy Ending, I did enjoy this series but that time I was super busy with uni and had to place it on hold. Now when I tried to pick up from where I left off I just couldn't get into it at all now....don't know why but it became boring for me. Moorim School I couldn't stand the bad acting and lack of plot (I've been following recaps on it...so that one I'll leave as dropped). For Madame Antoine, since I'm in a research field myself (I'm a medical science research student), MA irks me because it's unbelievably unrealistic.... that's not how a research is conducted in real life and a lot things the main lead did in there is unethical. But thanks so much for your suggestions! I'll definitely give Marriage Contract another chance :) since you don't have a dropped list, I'll go back to @Minyoung...
@Minyoung haha I didn't understand her fangirling either! Her screams I agree were rather annoying and she seems so immature! But if you look past that and give the show a chance it really is heartwarming. All the Reply seasons are so heartwarming. The main girl does get better over the course of the drama. Definitely give it another shot! As for other recommendations, if you love Yoo Seung Ho, please do give Imaginary Cat another chance - the real OTP is his relationship with his cat. It made me cry towards the end and the good thing is, this drama is a mini series so It's really short. The other drama that many people have recommended me is The Producers. I personally have not watched it yet but I hear that it gets better by episode 3-4 onwards :) with Jealously Incarnate, thanks for your suggestion, I'll go back to it after I finish O2O. I dropped it initially because I fell asleep while watching the first 3 episodes, however if it gets better by episodes 5-6 I'm willing to give it a chance ^^
