I have a number of favorites for different reasons.
Intertwined by Ikuhana Niiro. My favorite thing about this artist in general is that when you read one of their chapters, they make sure that you're experiencing a moment in their characters life. I really enjoy the realistic banter between a lot of their chapters and this one isn't an exception. Two friends meeting up from online and when it comes time for sex, a lot of times the first time with someone is a little awkward especially if you have some insecurities and just expressing them and reassuring each other is really cute. I can't get enough of this artist honestly.
Mantis Girls by Kisen. I love how expressive the girls faces are and the undertone of this chapter. This artist does a wonderful job with expressions and line work.
Irregular by Key. I love the minimalist art style of Key while maintaining a eye for detail in everything they draw. Seams, and buttons and buckles and tags on clothing and texture on tennis shoes. The way they draw pubic hair and how wet spots form on underwear etc.
Life is a Battlefield by Fujimaru which is a small series of a rom-com between a male artist and his manager. I think it's one of the best rom-com's we have on the site.
I have a number of chapters I really like, but unfortunately a lot of them fall in books since that's where my nose is in most of the time. I have a lot of random chapters here and there from various books that I adore.
