I think it might be kind of a joke. Asami feels that Aki is kinda tormenting him with all the cute stuff so he has to be like "ok, I give in, stop that please" instead of ignoring it.
And as Asami is not the person to plead it would be kind of surrendering x)
Asami thinks Akihito is teasing him and giving him a hard time but Akihito is really just wanting to pair cute with scary because it makes his heart throb ・ω・
Well that is cute ヾ(☆▽☆)
That was really heart throbbing ლ(´ڡ`ლ)
What is he mean by " are u waiting for me to surrender " ?
