Hoshino Doubutsuen Koimonogatari

Kurihara, a student aiming for art university, has always had the ability to see animals in humanoid form, and converse with them. Because of that, there's a bit of a distance between himself and others. He goes to Hoshino Zoo to sketch the animals and they often consult in him. Within the zoo grounds, there's a flame of love between a Parus major (great tit) and a small squirrel, fierce advance on the older lion from the younger lion, and sweet thoughts about the male zookeeper from an old penguin. Spring even comes to Kurihara...! You'll feel warm and fuzzy from reading these zoo love stories!
