The yaoi vibes clash with the tags that are claiming an R-18 Harem. The protag is dumb and the plot is ridiculous. Filled with unnatural cliche moments that immediately break you out of the story.
At one point some random rich dude that has his figure explained in detail is flirting with the protag in a cab after he stole it. Now that does nothing for me as a straight man secure in my sexuality, I don't care if a character is that way, but at the same time, I'm looking at the tags confused about how I got to this point. Know what I mean? The author said it was supposed to be funny. This was just one of the events like that.
Then there are the over-the-top cliches. The phone thing was where I dropped it. I'm not gonna bother going into them though. Just don't waste your time if you're bothered by any of this. Do not go in expecting the plot to move towards what the tags claim anytime soon. It's very boring even if you ignore what I've pointed out.
