Hayate is badgered into going to a mixer by his friend who was just dumped, and thinking that he needs something to jolt some excitement into his everyday life, he reluctantly agrees. Once there though, he can't quite get into the vibe and is about to leave when one of the girls approaches him.
There are just times when
 I can't keep up with them.
هناك أوقات لا أستطيع فيها ركوب قطار
الحماس معهم ومُسايرتهم
Ich kann bei deren Partylaune
bloß nicht immer ganz mithalten.
Mas há momentos que não consigo
seguir a empolgação deles.
Временами я не могу
поддерживать общий настрой.
