Is there repentance for a girl who was kissed by a young man, fearing her father's shock in the afterlife because of her action, knowing that the young man is her fiancé?

The girl should hasten to repent and multiply good deeds, for Allah Almighty says: "Indeed, good deeds do away with evil deeds." She should also thank Allah for His concealment (of her sins) and His guidance to repentance, and she should observe hijab in front of a suitor who is a stranger (to her). As for the Hereafter, whoever Allah conceals (his sins) in this world, He will conceal him on the Day of Resurrection, for the Prophet, peace and blessings be upon him, said: "Allah does not conceal a servant in this world, but Allah will conceal him on the Day of Resurrection."
