I absolutely loved this manga. Super cute. Would read again.
Siwon gets bullied and betrayed by his brother that had some mental problems. Got played by Joohoo and got bullied and r@ped. To the point he committed suicide. But Taemin got hit by a bus at the same time, so they body swapped. Taemin met his old friend who supposedly "abandoned" him when they were young only to be reunited in a new body and school. Siwoon noticed Taemin immediately and planned in Secret to make Siwon's brother crumple by teaming up with Joohoo.
