Red flag??

So I’m very new to dating and recently I’ve met a guy and we’ve only been talking for about a week. He says he really likes me and wants to start dating. I like him too but he’s already kinda clingy and he also get frustrated very easily and upset with me sometimes but he said he just really wants me to like him and really wants us to work out. Again, it’s only been a week! Because I’m new to dating I’m not sure which negative things to look out for. Is him doing all this a red flag at all? I can already tell he’s going to be a bit clingy but could it possibly turn into a more serious issue?
