Yumemiru Danshi wa Genjitsushugisha(2021)

Sajou Wataru, who is deeply in love with his beautiful classmate Natsukawa Aika, is continuing to approach her without getting discouraged while having dreams about their mutual love. However one day he woke up thinking "I am not really fit to be together with someone as good as her, huh..." Upon realizing this, Wataru started keeping an appropriate distance towards her, much to Aika's surprise. "Could it be that he hates me now...?" Did his intentions slip by her because she was getting impatient after arriving at the wrong conclusion!? This is the start of a romcom revolving around two people who just cant get their feelings across and both think their love is unrequited!
