Never Understand
Complete | Bbong | 2013 released
I loved this manhwa, but the side stories are a bit confusing and hard to follow through with, but the main couple had such an interesting dynamic and I adored how amazing they were together. For context, there are four gay couples, including the main one, and one heterosexual couple that doesn't have much screen time together, so I wouldn't consider it a relationship. Overall though, this manhwa is amazing and if you enjoy reading something that progresses rather slowly but sweetly, than this is perfect for you.
