Yeah I agree, but I think it was supposed to be a joke, brought on by a desire to have DG's time. The kouhai did say 'who're you running off to meet all the time? Spend more time with me!', so I think this is like a semi-joke from Alex responding to that 'Now you know we're dating and he's coming to see me so don't interfere with our time nya!'
Ummm asking your lover's friend to stop seing them because you are dating them is really toxic and thats the tea
