In Because I Love Her 2, the main characters are John and Claire, a couple who are high school sweethearts. These two are pretty happy but as they meet new people and make new friends that brings out feelings of wondering if they should stay a couple or not. They go through a cycle of meeting people, getting new jobs, etc, and you can decide if they stay on a romantic path or choose to live a corrupt life, it's all up to you. NTR is fully avoidable.
