One day Kaizuki is suddenly confessed by his junior at work although he replies with "that's impossible" right away he ends up thinking about the confession all day long. After a lot of thinking he ends up with the conclusion that his junior was just joking and messing with him so he confronts Igarashi and tells him to not make such a joke but it seems Igarashi was not kidding at all and was totally serious about his confession. After realizing this Kaizuki decides to serious reject Igarashi but Igarashi kisses him and declares that he is not giving up. Sorry is my explanation I'd kinda bad and confusing.
