Lovely★Complex centers on Risa Koizumi and Atsushi Ootani, two high school classmates whose biggest insecurity is the one thing neither can hide: their height. Risa is unusually tall for a girl, while Ootani is short for a boy, and both are painfully aware of how that makes them stand out. Their first crushes end badly when the people they like end up together, leaving them embarrassed, frustrated, and forced to keep running into each other at school.
What begins as constant bickering slowly becomes something warmer. As Risa and Ootani trade jokes, tease each other, and push one another through awkward teenage setbacks, they discover shared tastes in music and fashion and an easy habit of mutual encouragement. Lovely★Complex turns that unlikely friendship into a fast-paced romantic comedy built on timing, pride, and chemistry, following two mismatched classmates as they try to turn embarrassment into confidence and, maybe, friendship into something more. The series keeps its focus on how their differences become a source of comfort rather than shame, balancing slapstick comedy with sincere character growth and the messy excitement of school-age romance.
