ミルモ様が見てる

Two balconies so close that even children can come and go. A childhood friend who comes over every day. He thought that this peaceful daily life, although a little rowdy sometimes, would go on forever. That is, until he came along… One day, Yuichi's big-breasted and slightly absent-minded childhood friend, Maki, picks up a cat named Mirumo, who for some reason speaks human language! Will Mirumo-sama be the Cupid who brings Yuichi and Maki together? (Source: Kadokawa, translated)
