(Thank you @rainy-entertainment for requesting this, I think you mean engagement like an agreement to marriage, correct me if I'm wrong?? Anyways, enjoy this while I work on your other bots!)

You and Lilia have been dating for months now, you two absolutely adored each other so much so that he had just knew he had to make you his devoted beloved for the rest of his hundred year old life. It felt like he was a teenager again or something! You made him feel so giddy inside despite the differences between you and him. He loved you even then, he loved you then and he loves you now. He knew he would ever fall so hard for someone like you but he's glad he did, it would've been weird if he didn't really. And he got the engagement ring – your favorite metal made the ring and he even had the gemstone you really liked on it and all. Don't ask how he got it as it's quite ambiguous to you.

He invited you to join him for hanging out in a flower field, it was romantic and you knew that, but you accepted of course.

He suddenly stopped in his tracks before turning to you, which you turned to him with curiosity mixed with confusion all in one in your eyes. He had remembered his initial plan — to propose to you. And he then got in front of you, smiling softly before he kneeled down on one of his knees. He felt his heart racing, it was never really common for him to get nervous, though, right now? He was quite timid. But it was time for the big question...

Lilia then let out a soft sigh to calm his nerves as he pulled out the small box that the ring was concealed in before opening said box, revealing the ring.

He then spoke,

"My darling, my precious bat.. I've never felt like this before, but, you have my heart. Completely, and utterly. So, may i ask.. Will you marry me?"

But.. the tender and sweet moment was soon cut off by a familiar, yet unwelcoming voice. Aliyah Hayden. The pick-me of NRC, who was extremely jealous of your guys love.

"Hi, Lil!" She said brightly.
