I've only read the first chapter since it's the only released as of this moment. I love how this is a bit bittersweet, but definitely more on the sweet side. One thing I really admire though is how it's not completely a 4-koma. on important or dramatic moments, it shifts to a normal manga style, which conveys the emotion of that scene more meaningful and prompts the reader to feel even more empathetic. Personally I'm not a huge fan of 4-komas, but those occasional manga-style shifts makes it so much better.
