Average, but shows promise.
I'm going to be honest, even if it means being harsh.

The plot line is a cookie cutter story, that I've read before and has been done better. The typically flirtyassholebadboywithaheartofgold™ and the prissybitchygoodytwoshoesgirl™ hate each other but fall madly in love! It's been done before, it's boring, and it's not even realistic. There is nothing romantic about Drew's actions - he's constantly invading her personal space and basically sexually harassing and assaulting her because she isn't interested, yet somehow this is presented as an ideal, as attractive. Also, Megan is constantly called a bitch and a coward because she's sensible enough to not sleep around with the first hot guy she sees. This is a really annoying representation because it suggests that every and any girl with self worth who values herself and doesn't want to sleep around is somehow lesser. It's that really misogynistic "oh she's a prude" attitude and it's infuriating. Also, apparently Megan is the bitch character yet her sister and friends are constantly insensitive, pushy, cruel, gang up on others and don't give two shits about Megan's own wellbeing and feelings. I'd say they're the bitchy characters.
On the topic of the characters, they are also quite cookie cutter and plain. They feel flat, 2D, and so in line with the trope that I might as well be reading a "how to write a stereotypical romance, the example" book.
It's a shame, because your actual writing ability is really good. Your grammar and punctuation is near perfect and your style of switching perspectives, while it does have room for being refined, is very interesting and keeps the story flowing in a way you don't often see. Also, the first person has emotion in it which many authors fail to portray. You've done that really well and it could really shine, but an unoriginal story with an incredibly predictable plot line is sadly letting it down. At first glimpse, it seems like the story is there as an excuse to write lots of steamy moments. At second glance, it is clearly meant to be a story but it also becomes clearly generic. At third glance, we as readers are bored and looking for something new.
You show promise and I really think you could write something fantastic! But in order to do so I think you need to step away from the tropes and overdone storyline and create a genuinely unique, or mostly unique story that comes from your heart.
