Haru to Natsu

This is not a great story, in fact, I had considered dropping it all together after the first few chapters, but you could do a lot worse. The story is formulaic and it gets quite repetitive. However, the characters start to grow on you and some chapters in the second half of the series have some heart.

The main character is a stock standard submissive protagonist that mainly serves as an excuse for the sisters to compete over in humorous and sexy ways. The female leads start out quite two dimensional, but later on they do grow as characters. The slightly yandere qualities of the eldest twin are dropped in favor of showing her repressed lewdness and the youngest sister's constant oversexualied possessiveness grows fainter as she makes connections with others and starts helping them (in her own way). There are a few other support characters that don't really go anywhere in terms of character growth, but they are at least better than standard harem set dressings.

All in all, despite it being more ecchi than comedy, it was a fairly enjoyable experience that makes for a passable read.

Really inconsequential albeit enjoyable ecchi manga. It doesent have much to offer besides boobs, including an extremely generic art style, but both of the girls are cute and they have a great dynamic with eachother. Its main shortcoming is terrible MC Kiruma-kun, simultaneously a huge pussy as all ecchi harem mcs are, and a big pervert (manipulating his gf into embarassing herself into cosplay was kind of sus for him), and his personality switches every other chapter. Other then them there are a handful of woefully underdeveloped characters, like the fat guy whos obsessed with Natsumi, and the loli girl, and the other loli. Its nothing to really think about ever again after you finish it but its an alright timewaster.
