It seemed that she wanted to show off the house she helped build to the two of them and thus pulled them along the way.
Simon finally understood why the girl was so excited and eager to bring them here. The request from Fennel was just an excuse whereas her real motive was to surprise him and Irene with this house all along.
While Cecilia was still being smug about her work, Fennel coughed once before reminding "How long do you plan on putting that act? Quickly invite the both of them inside… or do you intend to make them wait outside forever".
Being scolded by Grandpa Fennel, Cecilia immediately realised her mistake and made a flustered expression.
"Ah! Hehe… Big brother, Elder Sister welcome to your new home. Quickly come inside, let me show you around" right after saying that she came skipping in front of them and quickly pulled them inside.
