Had I Not Seen the Sun

Both are about two young, troubled high schoolers who find solace and belonging in each other. They also tackle darker themes like school bullying, child neglect, etc. Both ML's also end up in jail due to circumstances surrounding the FLs.

Both are stories centered around SA, how family members influence the decision of whether or not to report, stigma, corruption by those in position of power, and the emotional toll of it all.
