A young boy experiences a breakup with his girlfriend, grows up around the age of 15, and potentially has a mental disorder

a young boy experiences his first love and grapples with a potential mental disorder. When he was around 6 to 9 years old, he loses his girlfriend under uncertain circumstances, whether due to an accident, illness, or relocation. As he grows older, around 14 to 17 years old, he falls in love again with a girl who resembles his first love in appearance and age. This creates uncertainty and raises questions about his true intentions, as he only feels attracted to girls with similar characteristics.

(probably released between 2010 to 2018).
