My Cat Girl Neighbor Is Impossible to Understand

In a peaceful world where humans and beastfolk live side by side, quiet high school student Sui Aoyama never expected his ordinary life to change. Everything begins when Yuiko Nekozawa, a reserved cat girl with a sharp tongue and an expressive tail she can't control, transfers into his class and moves in next door. As the two awkward neighbors spend more time together through school, walks home, and everyday moments, their friendship slowly blossoms into a heartfelt first love. Filled with comedy, warmth, and the charm of ordinary days, this is a slow-burn romance about finding someone who understands the feelings you can't put into words. — Description from novelcodex.org
