Misoshiru de Kanpai!

Zenichirou is a middle school student raised in a motherless family. His breakfast always consists of onigiri and instant miso soup from the convenience store. Yae, a childhood friend of Zenichirou, cannot stand to see him eat such an innutritious breakfast, so she decides to make him breakfast every morning... This story conveys a simple message: eating with another person makes miso soup taste more delicious and hearty! (Source: Shogakukan, translated) Included one-shot: Volume 1: Seishun Re:verse
