The boy who has been dating Kashiwagi, thanks to Shirogane's help, comes back yet again for more relationship advice from Shirogane. But something seems different about him. With his return from summer vacation, he has completely transformed into a player. Getting advice was just an excuse to brag about his girlfriend to Shirogane and Ishigami, and the two suspect that he has "experienced nirvana." They decide to leave the couple alone and observe them from afar as the two lovebirds start to get into a romantic mood...
so he refuses to tell her his birthday.
.لذا يرفض إخبارها بعيد ميلاده
und macht aus dem Grund stur
ein Geheimnis aus seinem Geburtstag.
y por eso se rehúsa
a decirle su cumpleaños.
por eso se niega a decirle 
cuándo es su cumpleaños.
voilà pourquoi il s’obstine
à taire son anniversaire.
इसलिए उसने उसे अपना
जन्मदिन बताने से मना कर दिया।
então se recusa a
dizer seu aniversário.
поэтому и отказывается назвать
 день своего рождения.
