Just as Irish promised, she left together with Olivia and Edward after she finished giving Adrian her love advice.
It turned out that it was actually their eldest brother whom she mainly decided to visit there - not him. That explained why the three of them were together. She confessed that she was only messing around when she said she went there to see him and poke her nose in his business.
"Or so she said. You do know Irish, right? From now on, she will most probably use me as an excuse to see you again..." was what Edward told Adrian before they left his office that time.
"Hopefully, your doors will still be open for us, Adrian."
Even Charles was somewhat impressed by the love advice that Irish gave. There is no underlying tone or hidden agenda behind her words. She was advising him with a pure and genuine intention, completely disregarding their strife and falling-out for a moment.
