It's about a Yukkuri Marisa that is brought to her new home. Her owner is a buff guy that tells her to TAKE IT HARD. This confuses the Marisa, so he explains what he means. He says the best things in life are not earned easy. Or that to take it easy and help others take it easy, you have to take it hard. I forgot the specifics. There is third-person narration.
He makes her exercise to get her food. She has a cat house with ledges that she climbs to reach her food. Marisa's food is like a solid brick that she has trouble biting through. She has to stretch-stretch to reach the rabbit water bottle that is just slightly high. There might have been some other workouts in the comic, but I can't remember them.
Anyone know which comic this was? I can't remember if I had seen this comic posted to OYP, or somewhere else.
Editing after the answer was given to me: because I had afterthoughts about not letting other people see spoilers.
