My Ship's Characterization Is Toxic

Also known as "My Boyfriend's Character Setting Makes No Sense" and "I Must Have Offended the Author in My Past Life." Since the male lead offended the author, she made one male lead (with one character design) play the parts of every male lead. And his love interests are always bizarre! A superstitious domineering CEO, a cross-dressing martial artist built like a muscular Barbie, an emperor obsessed with erotic paintings... The male lead: Are you sure you only use one character design because you're broke? The love interests: What did I ever do wrong? This story contains multiple arcs, but the male lead and each love interest only have one character design. The first arc features a blunt, aloof top who's obsessed with hands, and a sunny, superstitious, wealthy bottom. Love interest: Let's go on a date at a temple! I found one that's really effective. Love interest: Let's move in together. I'll put a mirror in the bathroom. Love interest: Let's go see a movie! The new horror film is hilarious. Male lead: But I only love "Approaching Science"... The point of view will be stated at the beginning of each arc's first chapter. My writing isn't great, but personal attacks are not welcome. Theme:
