He said he'd never break up with her. But lately he've been acting strangely, as if... avoiding her.
She couldn't tell what was happening to him, but one thing she knew: he was worried. She could sense that through his words, through his eyes, that were the windows to his soul. She knew for sure, something was wrong, and it had something to do with that 'business' of him, she could sense that, too.
Tsuna wasn't like that, she knew. He'd always have that smile on his lips, telling her how much he loved her or how he'd protect her until the end, even though she didn't even knew in what she was- indirectly- involved. Tsuna knew that, but he couldn't help but to fall in love with her. He thought what'd be her reaction if she knew what she got herself into. He loved her more the anything, and couldn't stand losing her.
Deep inside he was afraid- no, desperate-, that she'd leave him, break his heart once again, like it'd happened once.
- [name], we need to talk. This could be his last chance.
He'd tell her all the truth. Everything. Even things only he knew, because she was his fianceé and she deserved to know. According to Tsuna, she'd be the happiest woman in the whole world. And she only needed him to be happy, both of them were sure of that. The passionate kiss they shared after that showed that now everything was alright.
She'd stay by his side, and he glady accepted that. Having this in mind, Tsuna knew his way would be even more secure and bright, after all, [name] would be by his side. Forever.
