The day the two met, Kou tried to exorcist Hanako. Nene protected/defended Hanako, when Kou had looked at Nene—he blushed. Kou usually blushes and sometimes stutters around Nene hinting he has feelings for her. Eventually after the ”rocky start”, Nene and Kou got along well. They’re shown hanging out together and with Hanako.
In the Misaki Stairs Arc, he and Hanako protected Nene from Yako’s giant scissors. Kou made sure Yako’s moving dolls didn’t get near Nene. In the Clock Keeper Arc, Kou had been turned older by one of the supernaturals. When Kou was turned older, he looked like Teru. Nene didn’t want to “accidentally“ fall in love with him, so she tried to avoid him. In the Picture Perfect Arc, Nene and Kou noticed their supernatrual/dead friends were students. They worked together to find out why they’re students when they’re supposed to be ghosts. When they had to clean the pools, they hoped to see each other so they can continue discussing. Nene and Kou were running towards each other for something that looked like a “hug”.
Whenever Hanako teases her, Kou is quick to defend her. Whenever Nene is insecure about her obese ankles, Kou lets Nene know she’s still cute. He is obviously shown to be supportive of Nene.
He once pretended to be an awful cook so he can get Nene to help him make donuts for Hanako. He was apparently really close with Nene and barely noticed, Nene told him how close he was and he backed up in embarrassment. Kou was also seen upset when he found out about Nene’s shorten lifespan. Since then he was more protective of Nene and wanted her life to have a good fate.
The ship Kounene is one of the “underrated” ships in TBHK. Since Hananene and Mitsukou is one of beloved ships, this ship isn’t really admired by many people. It’s implied that Kou has romantic feelings for Nene when he first meets her, but it isn't often seen anymore in most recent chapters.
- During one of the arcs, Nene almost fell in love with Kou.
- Kou’s type is a person with a cute smile.
