Haaaaa, ungrateful humans in the beginning. It's a medium-strength tear-jerker in the beginning, and the start is pretty good and well done.... also fluffy
It's really rare for a manga to make me grin like a creep, and this, is one of those rare manga. The art are nice to see, the protag are really pure to the point that she heals everyone. I just love it.
only issue i have is that winter is not really needed, like winter does not give any boon to anything i personally know of..maybe some rare animal or plant but i think 95% of things would live easier without winter, of course i don't mean that the temperature goes up instead but just no winter like in the tropics.
