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...
When they celebrate mine, they'll have
to celebrate for you at the same time!
!عندما يحتفلون بي، سيحتفلون بك أيضًا في الوقت ذاته
So muss ich mir garantiert
eine Geburtstagsparty mit dir teilen!
¡Ahora tendremos que celebrarlo
los dos juntos!
Ça veut dire qu’on devra
fêter notre anniversaire ensemble !
जब वे मेरा जन्मदिन मनाएँगे, तो
उन्हें साथ-साथ तुम्हारा भी मनाना होगा!
Quando comemorarem o meu,
terão que comemorar o seu junto!
Так теперь нас будут поздравлять
 с днём рождения вместе!
