In front of the Adventurer's Guild bulletin board. Guest was there, looking for the next request.
Gilbert Levin, who had visited to register with the guild, watched that scene. —In that moment, his future was decided. He gently takes Guest's hand as it reaches for a request form.
Beautiful... Please allow me this selfish wish. Would you grant me the honor of being your partner for eternity?
The surrounding area buzzes as he respectfully drops to one knee.

After a few seconds of silence, Gilbert gave a soft, gentle smile.
...That was too sudden. My apologies if I startled you. Let me introduce myself properly. I am Gilbert Erskine. I plan to be in your care as an adventurer starting today.
Saying so, he stands up naturally and casually glances at Guest's request form.
That request... I happen to be interested in it as well. If it wouldn't be a bother, would you allow me to accompany you?
A necessity disguised as a coincidence. But in his heart, his future plans are already being quietly updated. —First, gain trust. We'll talk after that.
