Preliminary (8/63 eps)

Eruko's stay at home money has almost run out, and her alter erotic alter ego Eroko on twitter may have 100k followers but that is not going to pay the bills. She has to get a part time job to help her pay for her stay at home lifestyle. She has a weakness for hi-school boys, even though she is now 27. And her new boss is... yup.. a hi-schooler. Now she has to keep her alter ego down and get work done while she lust after the 17 yr old.

She suppresses her urges.. barley, but after some near misses, ...

Ok so you probabbly thinking this manga is going to be those one trashy romcoms out there where they take 140 chapters just to confess to oneanother. Oh boy you are wrong. This manga takes things to a new perspective were a girl is the one who is thinking, the protagonist. I saw many romcoms where a dense guy character is the pov. This one has a neet busty onee san in her near 30's fantasizing everything that makes her h0řny and in her case, a 17 year old highschool boy. This manga is great for all genders considering the protagonist a girl and the ... other one is a guy and the writer does their characters amazingly.

This manga shows genres I didn't see executed so well before. A female neet protagonist nailed it, an interesting backstory nailed it, and of course the age gap. They also nailed eachother 😏.

Its so refreshing to see an adult relationship with an age gap. Its unique in my eyes since all I see is highschool romcoms EVERYWHERE.

I know couple of friends in real life that has huge age gaps relationships and this nailed it on how they feel at their first few months. Anxiousness, fear of loss, legal terms (OC) I literally know someone right now as I type this review a 17 year old guy in a relationship with a 25 year old woman) family approval and experience in dating as a whole. That new layer of plot adds to what the characters feel and this manga stays true to it. The age is such an interesting point in this manga and the reason I love it. On how they will soon turn out and what conflicts they may encounter.

I already love trashy romance manga's and anime's and this is one of the best reads I ever read so far. I love the writing so much and how attached I got to the characters and how they feel. It feels surreal and genuine at the same time.

The art is great but can do better but it suffice and still amazing. Eroko San is so hot and so is Hisoka I think I might be bi after this series ends. Also hand holding is not the only thing you will see here, wink wink. Yes I am looking at you doujinshi lovers and cultured men and women you will certainly like this part of the manga.

Characters are already with the story and art I'm still madly in love with them though.

I enjoyed this serialization way too much I finished 24 chapters in 3 hours. It's that enjoyable for me. Every chapter is new and interesting it will make you go read it. The cultured way of art also brings me back, wink wink.

I will edit this review once it gets another 30 chapters or so or when its finished. Either way if you made it this far to my review congrats you read my obsession journal to this manga.

It is a must read for people looking to a refreshing romance. 10/10 indeed. Also I love onee sans. Onee sans love and protect. Ja na!

*Rapid Review*

As of chapter 48:

WARNING: This is a romance between a male minor (17 yo) and an female (27yo) adult. And it is sexual. Very. Though it's not shown. So if you can't handle that sort of stuff, don't read this. Though as of the late 40's, the male becomes 18 years old.

But other than that, it's a decent 6/10 romcom. The relationship between the characters evolves gradually once they get together as they come to be accepted by each other's family as well as accepting each other's quirks. But it's not very eventful. There is very minor drama, the plot lines are somewhat entertaining ...
