It was Dipper and Mabel's eighteenth birthday and she hadn't felt true love since she left Mermando.

What has he been up to lately? Is he alright? How is he?

There was absolutely no way that she could contact him.

So Mabel escaped from the party that Wendy and Soos planned for the twins and sat out nearby the lake.

I wish he was here.

The girl took off her shoes and waded in the water. A hand then grabbed her foot. She screamed and tried to pull back.

Whatever the creäture was, it laughed. And it laughed hard. The creäture let go and revealed itself.

"Mermando!"

Mabel jumped into the water and squeezed him.

"Yes Mabel. I am here. I could not resist to come on your eighteenth birthday!"

Something kicked Mabel. "Ouch! What was that?"

Mermando stood up. "Sorry. I am not used to my new legs."

She was speechless. "You...legs...how?"

"I was old enough to get some legs! It is a very long story."

"Either way, legs or no legs, I missed you!"

"I came here to take you out on a birthday date."

"Oh! Wonderful!"

Mermando came out of the water and Mabel came out next to him.

It took some drying off but eventually, the two were dry.

He wore some skinny jeans and a baggy sweater. Mabel had her usual sweater and skirt which was still wet. Oh well.

Mermando led Mabel to a little restaurant near the edge of town. It looked like all seafood.

All the boy had to do was smile and wave at the chef and hostess and they were seated at a hidden booth behind a fountain.

"Do you know the owners of this place?" asked Mabel.

"Yes. They are my aunt and uncle. This place is brand new! Ever since we got a machine to get legs, mermaids are all inhabiting land!"

A woman who resembled Mermando came in and handed the couple each one menu.

"Hello. You must be Mabel. I am Mermando's aunt, Mermia. Would you like anything to drink?"

"Nice to meet you! And I would just like some water," replied Mabel.

"Fresh water please. Thank you."

The two talked for a while and then ordered their foods.

They ate and talked when finally, it was over.

"There's one more thing I have planned for your birthday."

He then took her outside to the lake where a boat was waiting for them near the dock.

Mermando helped her get in the boat and then he got in himself.

The teen paddled the boat until they reached the middle. Mabel sat next to Mermando and laid her head on his shoulders.

"Thanks for coming. I really appreciate you coming back for me."

"Anything for you, my love."

Mabel sat up and looked up at Mermando.

"I really missed you."

"Me too. But I haven't given you my gift yet."

The teenage boy took out a pearl ring out of his pocket. "This is a promise ring. If you take it, you promise me that you'll never leave me."

Mabel put on the ring and looked at his eyes.

He really did truly love her.

She then leaned in and laid her lips on his. The whole world was ignored. The sounds of the birds were gone. All they focused on was each other.

When they pulley back, Mabel smiled said, "I promise."
