This is a solid story that takes place during the 3rd year of high school, a period many manga and anime avoid. It has very little drama or "interesting" events, but watching love escape from friendship and bloom is wonderful!
Both Natsuha and Yuuki are pretty complex characters for the tropes one might expect from them. They are innocent but not overly dependent on one another: in other words, a good couple. Their story is very simple and realistic, fitting the high school slice of life themes perfectly. Just don't expect a lot of comedy in this romcom.
7/10 I initially was considering giving this an 8, but I actually had to take a break while reading since it was so flat. I do recommend reading this, but only if you want something really mellow and relaxing. It is good, and sometimes people need something good rather than life changing.
