Now college students, Narasaki and Terashima have moved in together. If this cohabitation greatly strengthened the bond that united them, it was without counting on the arrival of Kurisu , a young man whom Narasaki met during his driving training. During the discussions, it turns out that Terashima and Kurisu are not completely strangers... in fact, the young man had pierced Terashima 's ears in middle school! Narasaki , for his part, is far from delighted by this discovery, especially since the two young men attend the same university and will have to cross paths regularly. And the worst part of all this is that Terashima doesn't seem to leave Kurisu totally indifferent...!
