Koi Kaze, Koi wa Ameagari no You ni Recommendations
Age gap romance anime well made. If you think Koi wa Ameagari is doing it well, then you'll sure think the same about Koi Kaze - and the same thing the other way around. Both deal with age gap love in a mature way, making sure to present the problems age gap couples may face without fetishizing or being silly about it.
Koi Kaze deals with the theme in a more hardcore way, since there's not only the age gap taboo, but also incest.
Both are very melancholic, but Koi wa Ameagari no you ni is lighter since there's a slight comedy in the middle
Koi Kaze and After the Rain both deal with a relationship that can be seen as taboo.
After the rain deals with a high school girl who falls in love with her noticeably older manager at work. Koi Kaze also deals with this age difference, but also adds a blood relationship between the couple to create drama.
After the Rain focuses on the female protagonist, Tachibana, while Koi Kaze focuses on the male protagonist, Koshiro.
While After the Rain is a more lighthearted and comfy show, Koi Kaze delves into the taboo aspects of the relationship and approaches a more realistic and dramatic take.
