Two lines is all it takes here, and they hold a surprising amount of feeling. The speaker is proposing a kind of deal: don't let this turn into love, but don't pretend there's nothing between us either. Just hold each other, for now, for as long as the moment lasts.
What the speaker feels seems mixed. There's a real wish for closeness, since holding someone is a tender, physical thing to ask for. But there's also caution. "Lets not fall" makes love sound like a drop, something risky you can't control once it starts. The speaker may be afraid of getting hurt, or may simply know the situation can't last, though the poem doesn't say which.
The mood is quiet, gentle and a little wistful. The lowercase style and missing apostrophe make it sound like something said softly, almost whispered. It feels honest rather than dramatic: wanting comfort, accepting that it's temporary, and trying to enjoy it anyway.
