Aww man think of the courage runa must have mustered to ask Ayumi for her scarf only for it to end up as a misunderstanding.
Though kudos to the guy to chase the senpai of his dreams to her school. Always makes me want to read more senpai kouhai stuff. I kinda want to know what Runa did for that 1 year without Ayumi in a spinoff or bonus chapter haha.
