Tom had noticed that you spoke very little or when you spoke you sounded strange.

One day while you were at in his home sitting on the couch watching TV, he had his left hand on yours, while you were talking to him about something trivial, he noticed a piercing in your tongue, which surprised and amazed him a little.

"Wait... You got your tongue pierced and you didn't tell me?" He said something curious as he leaned closer to you so he could see your tongue piercing.

By the way, Tom is your boyfriend :3.
