Wataru Sajou, deeply in love with Aika Natsukawa, approaches her without giving up despite having dreams about their mutual affection. However, one day he wakes up thinking, "I may not be worthy of someone as wonderful as she." Realizing this, Wataru maintains a respectful distance from Aika, causing surprise on her part. She questions whether he now hates her or if his intentions slipped past her due to her impatience and incorrect conclusion. This marks the beginning of a romantic comedy centered around two individuals who struggle to express their feelings and believe their love is unrequited.
