Soooo incredibly cute. Family shenanigans and sweet romance with lots of fluff, a perfect easy read! Don't go in expecting a complex plot or deep character study - the story is a simple romance, but it's perfect for what it is.
All the characters are lovable (especially Ayu!) and the author is very kind to them. No unnecessary angst or drama, but enough minor conflict for the characters to deal with to keep it interesting and progressing. Plus some humor thrown in for good measure. Happy ending was very honest and heartfelt, and felt well deserved.
Definitely check it out - it's a great pick me
