Warm

Megumi Shimizu's life is routine and monotonous. Get up, go to school early, fulfill her duties as class leader, try to deal with Inoue, and go home and do it all again tomorrow. She has no friends, her life doesn't seem like it'll go anywhere...and she's fine with that.

She's used to it, just like she's used to the cold, numbing winters in her hometown of Ikigai.

Then one day, a new transfer arrives. A new transfer who is instantly liked by her classmates and teacher, who is everything Megumi is not. Bubbly, sweet, happy, social.
And for some reason, this new girl, Hinata Mikami, thinks Megumi is nice and wants to be friends. And Megumi is stunned to find she likes Hinata too...

Little by little, Megumi's cold and unfeeling world sounds less and less appealing.
