Taemin suffers Depression, Schizophrenia, Hallucinations, Delusions, Paranoia, is bullimic and anorexic

Taemin is GAY.

He had a partner that threatened the boy to give birth to a child unless he wanted the two to break up.

Taemin complied.  However, when they entered the hospital while Taemin was in 'labor' doctors had the two shipped of to a mental institute for beind delusional.

Taemin was angered by the fact his 'baby' was taken away from him. 

He managed to escape the asylum he and his partner were locked in and he never looked back to save the man. 

His baby was much more important.

Then, he stumbled upon an asylum, the "a₴уlцм fоя тнё мёитallу їи$aпё" where he met young patient Key, patient Minho and caretaker Jonghyun.

From the start he was suspected of not being who he said he was and they were right, he wasn't Caretaker Taemin.

He took in the boy with peter[an syndrome who was dating the caretaker Jonghyun aka "prince"

Little did he know his baby was on the road to recovery and had sensed and maybe discussed with Jonghyun about Taemin being odd. 

The duo, had Taemin take the psych test while he was unconcious one day and ever since then, Taemin re-registered in a mental institute under heavy guarding. 

Taemin doesn't trust anyone other than Minho, another patient he met in the institute before and after he became a patient. He is also known as "Prince Froggie". Taemin still wishes to see him but doesn't know about the latter.

Taemin refuses to trust anyone anymore and is willing to do anything to get out of here!
