these titles confuse me @A@

They all related at some point. But you can read each one without needing the others just fine.

I only read the manhwa, not novel. So, what I know

Contains r*pe
Kiss me, liar
Kiss the scumbag

Without r*pe
Kiss me if you can
Desire me if you can

For kiss the bride, I haven't read it

—Eat Me Up If You Can (Grandfather Dominic's generation)*
—Lick Me Up If You Can (Father Ashley's generation)*
—Kiss Me, Liar (Keith - Grayson's friend)
—Kiss Me If You Can (Chase )
—Run Away If You Can (Nathaniel - Chase and Grayson's brother)*
—Desire Me If You Can (Grayson)

"*" Means haven't released here

I think they all look interesting and need to read all series to understand all story since theyre all related.. but if i were to re-read all of them i would skip "kiss me, liar" Keith's story .. it was interesting at first (for me) but if you keep reading it you will start to hate all characters lol

Chase and grayson story are my fav. (Based on what ive read so far)
I like how chase are cute and changing because of love (ahh the power of love are just magnificent isn't it?)
About Grayson's story.. all i can say is Go suffer more u damn lunatic,. And show more Dane body pls (つ✧ω✧)つ
