Here is how Sunshine Through the Rain is have the vibes to Lighter and Princess:
1. It makes you want to study. Both main leads are super smart and hardworking, which really motivates me (maybe you too) to study hard.
2. Both stories take place during their university years and transition into their post-graduation lives.
3. Deep, slow burn, and healing romance. They're both melodramas with complex characters who carry their own personal trauma and heal together along the way.

This is 100% my taste, and I bet it's yours as well!
