She is a sleep-deprived and hard-working girlfriend, but when she sleeps, she's a cheerful girl whose words are just snores and zzz.
She's just like me frfr. The sleep-deprived part tho.
My guess is a weeaboo extraterrestrial girl who wants to study the planet's 'culture' (anime and manga) and wears a freakishly big hat to cover up her antennas.
So this degenerate Sonic guy is criticising every single girlfriend in this manga that is absurd enough and has said many times he quit reading, but always came back just to criticise without reading the whole chapter.
Also, quick minor details to the ramen chef. Each new challenge dish she makes has an outcome. The hot as hell, sweaty. The steamy-as-hell, assault to the eyes. Tough-as-hell, chipped tooth. Messy-as-hell, sauce all over her.
This guy's sole purpose in this manga is to criticise every girlfriend. I think he's just a masochist like Iku, but more pathetic. It's a haha funny manga. It's not based on real life.
My guy. The manga title alone is crazy enough. Do you really expect one girl out of 100 Ratarou's girlfriends to be normal? Also, it's a romcom. Not romnorm.
