I recommend you to watch Goong as well as I Remember You. I will admit I'm a bit biased towards Goong, but I truly believe it's a good 'classic' drama. Even though there's drama, it generally makes you feel good a lot and fall in love with the main characters. Not only that, but the family of the female main char is super adorable and memorable :)
I remember you has great bromance (I'm still watching it though). I'd mainly recommend it if you like psychological stuff. There's subtle romance as well, but I would say it's not the main focus. Also, there are quite a lot of twists and turns in the beginning. As confusing as it is, stick with it because later on things will be quite obvious, yet still super enjoyable because you want to know how it'll all end (up for everyone). Never a dull moment imo
