For what its worth, Asagi's 'real milk?' initial reaction is "honmono?"; she's asking if this is actually milk, referencing the toothpaste milk from Ch. 26.
The "its alright" is daijoubu which can mean a ton of things including 'safe'; I think the joke here is that she was waiting for Ena to drink it first to confirm its actually milk.
