Xen's "Happy Beginning" is a short, quiet wish. The speaker hopes for a fresh start where they can be themselves, love who they want to, and live as the person they feel they are. The poem doesn't say what stands in the way, but the repeated idea of being free to "be myself" suggests that right now they can't fully do that.
What stands out is the shift in the last few lines. The speaker begins with "I hope," which sounds gentle and uncertain, then moves to "I'll wait my whole life / If I have to." That's a big leap. It shows patience, but also a kind of ache, because waiting a lifetime is a heavy thing to promise. The plain, simple wording makes it feel honest, like something said quietly rather than performed.
The mood is hopeful but sad. There's longing in it, and stubborn determination too. The speaker refuses to give up on the idea of a happy beginning, even if it takes forever.
