Not the best in terms of actual romance, but it was really realistic and cute. This will contain spoilers. The story was short and every chapter was sweet. I do have the complaint of never seeing them as a couple, as when Yutaka confessed, the manga ended. The whole manga was really heartwarming. The art isn't too unique, and there are some panel that are text boxes with a white background and some gradients. But, it didn't bother me, which is the most important part. The character art for Karin was cute, and the flowers were not rushed. The characters were thought out and real. Yutaka was relatable whenhe didn't want to approach Karin who he liked and with his flustered reactions at the beginning when the girl talked to him.
Karin was very likeable, as she didn't show signs of prejudicing people. (Also her character art and when she's flustered)

I enjoyed this short read, and I would highly recommend this. But in the case that you are looking for romance with kissing and dating and hugging, this is not for you. (they didn't even have a kiss..)
