Kazuya has hardly begun to process the fallout from his birthday when he gets asked to go on another practice date with Sumi, this time with her taking the lead!
Only fools look back 
on the past with regret.
الحمقى وحدهم يغلبهم الندم
Nur Trottel bereuen es hinterher.
Arrepentirse es de idiotas.
Arrepentirse es de idiotas.
Seule une imbécile
éprouverait des regrets.
E pentirsi è una cosa che fanno gli sciocchi!
Não estou fazendo nada
de que me arrependerei.
Зацикливаться на сожалениях глупо.
