[Crossover] The English Rose

After an accident, 21-year-old Mycroft secretly took in 10-year-old Isabella Kilberd.

A year later, Mycroft was holding a book called How to Raise an English Rose.

Mrs. Holmes passed by, looking excited. "Oh, Mycroft, are you supporting my plan to raise Leah into an English rose?"

Mycroft flashed a grin. "After seeing all the ways English roses can die, I think you can call off that plan, Mother."

Mrs. Holmes: ...

Six years later, Mycroft was holding a book called How to Keep Other Men Away from the Woman You Like.

Mr. Holmes passed by, looking delighted. "Mycroft, have you got someone you like?"

Mycroft smiled calmly. "I'm worried that Leah might start dating young someday, and you'll end up sobbing in the bathroom, Father."

Mr. Holmes: ...

Fifteen years later, Isabella received a gift: a key to Mycroft's apartment.

She pursed her lips at the man across from her. "I thought I'd be the one to bring it up first."

Mycroft smiled with a hint of composure. "How could a gentleman let a lady be the first to propose?"
