Madonna wa Glass Case no Naka

This manga manages to balance between gross and beautiful. A man who faps to reptiles, owns a gecko and works at a reptile shop meets a girl who looks like a university student who is fascinated with the animals he's interested in.

Story:-
There's not much of a story to this except for how they both relate to each other by being different and distant from other people while learning how to love and care for the reptiles. The girl has her own difficult life which is revealed slowly as we go through the story. Not particularly interesting but not completely boring either.

Art:-
Quite attractive to show the various types of species of reptiles, the differences in physical characteristics and their way of living.

Character:-
Pretty average but enjoyable at the same time. One is the manager of the shop who is simply, put glasses and guides the protagonist of this series. There's another co-worker of his, who is straight-forward and talkative. The girl is sweet, scared and naughty at times. Meanwhile, the main guy tries to keep up with her by trying to be a supportive adult at the same time. (keeping his dark desires at bay LOLI ALERT!!!)

If you're fine with weird fetishes and unusually large-age gaps between people along with a passion reptiles, and having a thing for angst, you will enjoy this manga.
