Yagate Kimi ni Naru, Nettaigyo wa Yuki ni Kogareru Recommendations
Both stories are about the relationship between two high-school girls; a kouhai and her senpai. Also in both stories the senpai has something that doesn't show others except to her kouhai.
Yagakimi is more romantic while Nettaigyo is more about the friendship between the girls.
While both series focus on the relationship between two girls, YagaKimi centers around romance, while Nettaigyo (aka Hanigare) is more of a story about friendship. However, with that said, the similarities run rampant. Both exhibit coming-of-age elements, displaying how the main characters' relationships with one another aid in their own individual growth.
If you enjoyed one, I'm almost certain you would find the other to your liking. And if you're like me and suffered from a case of "the void" after reading YagaKimi, Nettaigyo might very well be the remedy you need.
Both works weave a beautiful and heartwarming tale of the developing relationships between two characters; while the work you (presumably) just read is shoujo ai in nature, Nettaigyo wa Yuki ni Kogareru (or "Hanigare" for short) is not.
YagaKimi's focus is on romance and a bond of blooming love between Yuu and Shouko, whereas Hanigare's focus is on establishing and cultivating the friendship between main characters Konatsu and Koyuki. They both start on a journey to overcome their respective social anxieties and slowly begin to fill the voids in each other's lives.
Sometimes simply being there for someone without needing to say anything is enough.
