Behind the scene: My Roommate Life #151, "All you can devour" (Patreon)

The original version of this episode saw Lony having a round belly on the last panel which was makind Beary's question useless: we can clearly see where Lonny puts all that food!

So Lony himself requested that he would look as he had eaten nothing at all, like many shonen manga heroes do after eating tremandous amounts of food.
