Let's address the elephant in the room here; Mao is packing heat, good lord. He's too tiny to be packing that much of a pocket monster. That bulge left nothing to the imagination at all. Having said that though, Mao is literally a human puppy with how oblivious and innocent he is. Do not lewd the puppy!
+1 to waiting for full chapters though. The half-chapter silliness that's been a recurring theme in many manga is a dumb thing. Good content takes time, and releasing an unfinished chapter is a stupid concept on the publisher's part (not the uploader, the actual company).
