At the university's badminton club's freshmen welcome party, everyone is scared stiff when the scary-looking Tougo introduces himself. The fearless (or maybe just clueless) freshmen Haruka ends up sharing a taxi home with Tougo... and while everyone else trembles in fear before him, Haruka finds him handsome.

From Girls' Generation Scanlations:
After attending a new member welcome party for his badminton club, freshman Haruka takes a taxi home with his senpai, the extremely scary-looking Tougo! Everyone’s scared stiff of Tougo, but the naturally airheaded Haruka just thinks Tougo is handsome. On the other hand, Tougo, who’s self-conscious about his looks, begins to grow fond of Haruka, who isn’t scared of Tougo at all. Tougo just can’t leave the clumsy Haruka alone. Tougo wants to do something to help Haruka out, so one day, Tougo tells him, “Go out with me”...?!

19-year-old Roji Shizuru has a crush on a fellow university student, Nana, but there always seems to be complications when he tries to get closer to her. For one thing, he's afraid his hot friend Tachibana Masaki will steal her. Beyond that, the main complication comes from the interference of children, specifically one odd child called Maida Kokoro, who keeps clinging to Shizuru and calling him 'mama.'

Since middle school Bun-chan has been hanging out with the male/female childhood friend duo that is Choco and Suzu. And he's jealous of their closeness—partly because he wishes he could just generally be as close to them as they are to each other, but he has another reason: he's in love with Choco, and it seems like just a matter of time before Choco and Suzu start dating. Choco constantly denies it, though–Suzu is like his adorable twin sister. Nonetheless, Bun has never bothered getting his hopes up. And even if Suzu's adorableness wasn't a part of the equation, it's not like Bun could ever tell Choco that he accidentally happened to fall for him one day when the boob-loving Choco jokingly groped his chest and Bun got aroused by it. So Bun is mostly happy with just being friends—him, Choco and Suzu forever! Or at least, that's what he'd intended…
