Yume no Owari de Machiawase

A pure and innocent story of unrequited love between childhood friends, woven together on sleepless nights.

In the autumn they turned twelve, Akito impulsively kissed Saku, desperate to not part ways from him. Six years later, Akito reunites with Saku, whom he lost contact with, at university. Though it's awkward, Akito's excited, so he musters the courage to speak to him, only to notice the dark circles under Saku's eyes. It turns out that Saku's been struggling with insomnia since high school! After discovering that he sleeps soundly when he's with Akito, Saku proposes, "I'll sleep next to you until I'm cured."
