>>30385981Mysta and Mika are best friends, Mysta tries to wingman for Mika whose trying to win Ike's affection but he obviously isn't into her. Mysta himself is trying to get laid but scares away any remotely attractive looking girl. Shippers want these menhera losers to get together, then the plot twist that they're both biological sibling separated at birth happens. Now a small number of shippers REALLY want them to be endgame.
Fuuchan and Uki are very close with eachother and barely interact with any female characters. They're the only reason this manga still has female readers. There's a lot of will-they-wont-they with just enough plausible deniability that make male readers believe fujos are being delusional again. By the end it's vaguely implied they moved to America to get married, whether their relationship was bait is still up for debate 5 years later.
