Chapter 80.5

Synopsis
In a time when being a big brother was still new to him, Ryuu wonders why Kotaro does not cry much. But, Kotaro is Ryuu's cute little brother after all, so Ryuu is always worried about him.

Long Summary
Kotaro quietly sits in a baby chair as Ryuu's parents panic to get their work done. Ryuu helps his father, who has a job in IT sales, find his passport, as he is about to fly to Fukuoka. Ryuu's mother, who works as a translator, laments the loss of the data of the manuscript that she had finished, but Ryuu reminds her of the USB that she saved her work on. Ryuu's father cheerily tells him that he is off to work and promises to bring souvenirs while Ryuu's mother asks Ryuu to take care of Kotaro as she rests for a few hours.

Ryuu panics as he realizes that he has forgotten about Kotaro and apologizes to him for neglecting him for a bit. Kotaro quietly stare at his brother, causing Ryuu to wonder if he has been sitting like that this whole time. Ryuu rocks his chair as he assures Kotaro that it is alright for him to cry if he would like Ryuu to play with him. Ryuu stops rocking Kotaro and sees that Kotaro has not even flinched. However, Kotaro's eyes sparkle, so Ryuu decides to resume rocking his chair. Just then, Kotaro smiles, and Ryuu realizes that Kotaro enjoys having the attention of his brother, despite not initially showing it.

Later, Ryuu gags as he changes Kotaro's diaper, telling Kotaro to cry when he needs a diaper change. As Kotaro is held by his mother, she tells Ryuu that Kotaro does fret sometimes when Ryuu is not home. She figures that Kotaro is really happy to see his big brother--happy enough to forget about crying. Ryuu blushes as his mother points out that he is flustered, causing him to become even more embarrassed as he admits to himself that he is also happy to see Kotaro.
