hmm..Issei words and facial expression when he want Nacchan to 'move it'..rub me the wrong way. He could've just say it in a nicer way, like, that's the guy you've been inlove with for 6 years. Not trying to be sensitive snowflake or anything, but that's not very nice and that small interaction could've become worse overtime if Issei can't balance out relationship and work.
