SPOILER FREE REVIEW
If I must say, it's 100x better than my expectation and if you're looking for a rom-com anime or simply love the art of super cute imoutos(MC girl is a super cute IMO)with a bit of harem, this will be one of my recommendation.
I found myself craving for more romance animes on this lonely summer holiday, thus lightheartedly picking up this anime after browsing through a lot of top 10s and such.
Anyway, I was blown away by the conclusion.
Story - The story is a not-so-typical-not-that-rare-either in the beginning but further development proves that everything fits just right/perfectly in their places and dang that last episode is very good.
Characters - I'm being biased but the characters' design are just perfect and their personality flows well with it. Btw,Love Tsukiko-chan :3 I love all the cute imoutos that there are and Tsukiko can be in my top 5 with that cute look of her.
Art - Enough said 12/10. As expected from J.C.
Sound - So-so but mostly at the good side. I found myself loving 'that one' instrumental that sometimes played in the back and the ED is cute and catchy.
Enjoyment - I ENJOYED IT VERY MUCH!!!
OVERALL - Very worth a watch for a romance anime. Got nothing on your list or just want to take a break with others anime or simply looking for another romance anime just like me? Go ahead pick this anime and it'll filled that empty void of yours.
