Impulses Ôkami kakushi : Season 1 Episode 3

Issei takes Hiroshi, Kaname, Isuzu, and Mana to the river for a picnic. Kaname and Isuzu go for a swim, and Isuzu accidentally drenches Hiroshi, using the opportunity to flirt with him. Issei lends Hiroshi his sweater, but when it is returned Issei begins acting strangely towards him. When Hiroshi develops a cold, Kaname directs him to Jōga hospital, where he encounters Shigetsu Kushinada, Nemuru's uncle and Jōga's head doctor, who prescribes him pills and takes a blood sample to run tests on. On the way out of the hospital, Hiroshi runs into Issei, who had followed him. Shigetsu meets with a man named Sakaki, who claims to be the head of a pharmaceutical company, and makes a deal with him. Issei drives Hiroshi home, but begins flirting with him, his eyes glowing red, and attempts to kiss him, stopping only when the hassaku juice air freshener in his car is shattered.
