so im trying to plan my next novel. And my plan is there's girls love (gl) and boys love(bl) in one book. The concept is: There are 2 couples with a healthy relationship and the 4 of them are both best friends but the other 2 are in a relationship so are the other 2 teenagers. But as their relationship lasted longer, the couples don't feel any love for their partner anymore, until the 2 girls(girlfriends of the 2 boys) is secretly having an affair with each other but never did the girls know that the 2 boys are also having an affair which makes in girls love and boys love. The story will focus on relationship, life, and life problems along with relationship problems such as lying to your partner and cheating.
