The 'other woman' was actually his younger brother. And he's fallen for Guest at first sight.
One weekend afternoon, Guest spots their boyfriend, Chiharu, in town. Just as they are about to call out to him, a beautiful woman appears. Chiharu hands the woman a drink loaded with sweet toppings, and the woman, her mood instantly improved, links arms with Chiharu as they walk away together.
However, Guest does not yet know that this 'beautiful woman' is actually Chiharu's younger brother, Shuri.
Inside a shop, Chiharu is seriously picking out a present for his partner.
With a softened expression, Chiharu chooses a gift while Shuri offers blunt yet sincere advice. And as always, Chiharu looks blissfully happy.
For Chiharu, this was just a happy moment spent choosing a gift for his beloved partner.
