The Real Reason For Staying Up Late ~Beginning~ Uryu dreams of a lost girl he met as a young child. Yae goes drinking with classmates. Fearing for her chastity Yuna and Asahi send Uryu as her bodyguard. When Yae does indeed draw a lot of male attention Uryu is forced to claim to be her boyfriend. Her childhood friend Makoto, an actual student at Tokyo Medical University, knows they are lying and takes an immediate dislike to Uryu whom she views as a freeloader living in Yae’s house. Returning her home Uryu finds Yae’s wallet and is surprised to learn from her driving licence her legal name is Reiko Ichijoji, not Yae Amagami. Despite the late hour Yae is able to convince everyone to visit the city with Makoto to see all her favourite night time spots. Watching fireflies at the river Uryu tries to ask Yae about her real name but Makoto keeps interfering. Asahi tries to ask Uryu if he prefers Yae to her but can’t do it as she fears what his answer will be. At a convenience store Makoto continues interfering between Uryu and Yae so he ends up sharing ice creams with Yuna instead. Seeing this, Makoto starts relaxing around him, until he suddenly asks her if she knows Reiko Ichijoji. This makes her angry again and she warns him that as far as Yae is concerned Reiko Ichijoji no longer exists.
