>>58580891It's a very common anime trope that healthy children get a tan from playing in the sun for a long time, just as it's a reality that women in Japan use a huge amount of skin-whitening products, since dark skin is considered unfeminine in Japanese culture.
This trope is very common, even among siblings. PR are a pair of Japanese siblings, but Takenori spends his time training basketball outside day and night, while Haruko isn't as hardcore with her training and usually just plays in the school gym.
