Review Detail of Stormzz in My Ultimate Crush is my Roommate

The story is pretty well paced, each chapter feels a good length to read, and there are updates frequently. The writing needs improvement. I noticed both tense changes and singular / plural mixups. I wasn't a fan of the characters, their dialogue felt off to me. The world could also be more fleshed out. It's not really a big thing for me in novels set in our world, but calling places "City A" and "City B" is just poor writing.
