Fated Mates - DRon (Draco x Ron)

The wizarding world is not only known to have wizards but also second-generation genders connected with them when they were born, that made them aware of their status, the Alpha, Beta, and Omega. Pureblood Alphas are born with a molten gold colored half-moon mark on their napes, while Halfblood Alphas have a dark red half-moon mark, while Pureblood Betas have a silver quarter-moon mark on their napes, while the halfbloods have a dark green quarter-moon mark, and lastly, the Omegas, which are only given the status of pureblood infants, a very rare gift in today's generation, including the Pureblood Alphas, are given the same gold but a full moon mark on their napes, which symbolizes a powerful fertile womb.

What if Alpha Draco and Omega Ron met earlier of their childhood inside the known wizarding bookshop (Flourish and Blotts) and was announced to be fated as Mates by their marks and with Molly's fear for her only Omega's child, she cast an obliviate spell with the two innocent children to forget each other's fated mate and cast a esconder spell to conceal both of their identity as a soulmate?

What will happen if the two meet again on their first year in hogwarts, but as a complete stranger again? And specifically became an enemies.
