"Taranta Ranta" ("Let's Go Happy Happy Girl" or "Looking for Happiness") 2 volumes by Youko Maki
Hikaru is optimistic to start her highschool with happiness. But on the first day she bumps into a guy who looks exactly like her dead brother. It's a signal of a tumultuous freshmen year.
It's like a oneshot stretched into 12 chapters. There are a lot of issues that didn't mature. The plot is anything goes. There are a lot of interesting characters that are not developed. Nothing happened, nothing was resolved. The manga needs a sequel to tie up the loose ends. But I was mesmerized by the beautiful art. The art reminds me of "Rockin Heaven". The reverse harem theme is not that defined but what the heck.
