making a proper egg and cheese (possibly w/ meat) sandwich from conbini ingredients is not too difficult if you know what you're doing, but I'm sad to say it can't beat a bacon-egg-cheese on a roll or bagel. father's coffee though probably can't be replicated.
@Qetuo There's quite a lot of stuff in this manga that's been edited from a picture of a real product and not drawn by hand. Just look at some of the weirdly specific details on the packaging for instance and you can tell that no one in their right mind drew that by hand.
You guys know it's pretty common for an artist to do that right? Saves time
There are some mangas which also make a living through sponsorships that way. You'll usually find it quite frequently in manga that has specialist themes - like Futari Solo Camp. That manga is chock full of traced products.
Imagine making money shilling a product you love with a manga you drew on particular subject matter lololol
I like the father-in-law. He's just a lonely guy who is having a little trouble letting go of his only child, but doesn't feel any resentment towards our MC.
