Iyaya Iyaya Mo Suki No Uchi?

Out of nowhere, Kaizuki is suddenly confessed to by his part-time job’s junior, the quiet and serious-faced Igarashi. Although Kaizuki immediately refuses and Igarashi says that he’s (probably) straight, he can’t get Igarashi out of his head. After a sudden kiss, will the future possibly hold romance for Kaizuki? Could he possibly love Igarashi -- yes, or no?
