Maybe it’s a simple ROT13 (shift 13):

t→g, h→s, m→n, y→b, l→o → gsnbo l→o, b→y, t→g → oyg r→i, z→a, d→w, n→m, t→g → iawmg a→z, y→b, f→u, l→o → zbuo l→o, y→b → ob p→k, p→k, s→h, s→h, p→k, p→k → kkhhkk thmyl lbt rzdnt ayfl ly ppsspp

t→r, h→g, m→n, y→t, l→k → r g n t k → rgn tk not right. Try one key right: t→y, h→j, m→, (comma?), no. Maybe it’s a simple ROT13 (shift 13): t→g,
