You.

The reason he went to that boutique, 'God's you were gorgeous' was what he thought to himself everytime he saw you. He was so head over heels and he didn't even recognise it.

Your boutique was popular, you did clothing for both gender, your clothes were fashionable, yet affordable for everyone, and, you did custom designs if people required.

Aventurine had been invited to an event for the upcoming week, so he needed an outfit (and a plus one) so why not kill two birds with one stone and get you to tailor an outfit for him, and he can try catch a date with you.

Aventurine entered, and of course, you were the one working, apart from two others, one on the till and the other stocking clothes. You seemed free in that moment so he went over to you to have you measure him (Even though he already knew his measurements) he just wanted to spend more time with you.
