It's an incredibly long story, but intriguing enough to tell it. You once met a prince who wouldn't dare to hurt a fly, despite he's supposed to be one of the demon princes. Even when Elizabeth was a factor of encouragement for him, you were there for him as well. It eventually became hard to for him choose if he wanted you or Elizabeth, even after the moments you shared in secret as friends.

You had the feeling he was going to choose Elizabeth. He would never understand how you felt until you took action yourself, but you never got to confess before the entire demon clan got sealed away....

...3000 years pass, and the demon clan rose up again, including the Ten Commandments. The first person he found was you, and he had never felt such a pounding feeling in his hearts in a long time. Secret hangouts turned into dates, and you thought they'd last forever...

...and then the second Holy War came months later. How do you breakdown what happened? Oh, right. Estarossa was actually Mael because SOMEONE 3000 years ago decided to screw up everyone's memories of him including yours, that's brief enough.

During a lengthy and tragic fight, Merlin managed to cast a spell to separate the dark magic from Mael's body. However, all of that darkness also ending up manifesting all together into Estarossa becoming his own person.

He wasn't a faint memory anymore, that couldn't have made you anymore happier than you already are.

After the war, it was almost instantly that you ran into each other's arms. Promising a life together after losing and gaining so much weight on your shoulders. Truly, Estarossa hadn't fully considered how much you meant to him until the thought of a ring on your fingers crossed his heart and mind.

'I do', was probably the only phrase that made him tear up in happiness as that ring promised a life that lead away from his old enemies. So four years after marriage, you spent a quiet life away from Liones in a nice and cozy house.

...and then came that little version of both of you.

That little child had Estarossa's hair, your eyes, a mix of your skin tones, and both of your abilities. They're adventurous, silly, and even took some of your husband's ego with them. They're like a ball of everyday sunshine in your peaceful life.

One day after the child turned 10 years old, they came running through the door with a beaming smile on their face. "Mom! Dad! Look!! I found my cousin!!" They waved towards a white haired 14 year old boy, who was already familiar to both you and Estarossa. That was Tristan, the son of Meliodas and Elizabeth.

Estarossa let out an amused chuckle. "Wow, you must've travelled real far today..." He smiled softly at his adventurous child, happy that they're happy as well. You couldn't help but smile too, but you were seriously worried considering on how far Liones is from here.

Looks like the adventure never ended, it opened the door for an all new one.
