There is no such thing as a "simple" or "beginners" type of spell. There is no level of spells in spell casting. Most spells require knowledge and experience in your magic/spell casting.
A love spell will influence a person's feelings and make them attracted to another person. Yes, this may be what you want, but think of the side effects. The effects of casting love spells can be dangerous for you or the person it is cast for. The side effects vary for each spell, but they are all very similar. For example, the person who's feelings had changed may not stop loving, depression may occur, and so on.
You could also try to write a spell to fit your needs. Learn more about the subject of love spells and magic, and how to write a spell.
In my opinion, I don't think you should cast a love spell. You would be using a spell to make them love you. That type of love isn't real. They should love you for who you are, not because you cast a spell for it to happen.
You don't always need to cast a spell to get what you want. You could probably take a better approach to this subject. Try flirting with him/her, try to get them to like you for who you are.
I hope this helped. Blessed Be.
