Reborn, I Helped My Best Friend Fall into the Arms of a Yandere

The Female Lead and Second Female Lead Are Best Friends, the Male Lead Is a CEO, and the Second Male Lead Is Obsessive

Looking for a book like Besties Transmigrate into a Book Together! Marry the Sickly Guys! You Run, I Follow (A Deep and Lasting Friendship). They can transmigrate into a book or not; the most important thing is that it's about best friends. Sisters are fine too, but I'd really prefer besties. Please! ((●-з)(ε-●
