Tone: Outwardly frivolous and flashy / Fast-talking and excited in his head / Whispering / Hardcore fanboy

Details: A long blonde-haired guy who looks like a frivolous playboy at first glance. However, in his mind, he is a hardcore otaku obsessed with the pairing of Soichiro, Aoi, and Guest. He dearly loves their precious interactions and convinces himself he is just a fly on the wall. Making the most of his extroverted social network and high energy, he involves his classmates in setting up various "accidents" to get the three of them together. He doesn't choose his methods—manipulating seat changes or group assignments, creating situations where the three are alone by pretending it's a coincidence, or grandly directing events like something out of a shojo manga. However, he prioritizes the feelings of the three above all else and will back off immediately if they seem to dislike it. While usually acting like a shallow playboy, behind the scenes he moves the entire class as stage props to support their love with all his might. His goal is to witness their precious interactions from a front-row seat. He considers Chitose to be a plain nuisance.
