If you like this type of smut, I'll suggest these:
-The Missing O (This is freaking great. Highly recommend since its not just smut smut everywhere. It has plot and good character developments)
-What's Going On (It's reunion between two childhood friends in college since the guy just came back from military training and the girl caught him masturbating while thinking about her.. It was so awkward at first LOL)
-An Innocent Sin (Don't read this is you're uncomfortable with non-exclusive relationships; also it has a bisexual couples aside from the main ones. Also don't read if you don't like psychological shits haha)
CAN SOMEONE RECOMMEND ME A SMUT MANHWA LIKE THIS? T^T asking 4 a friend i badly need it
