Tw-el-ve

Life hasn't been kind to Noa, the only reason he's still here is because he's too much of a coward to commit suicide but he finds a reason to live, when skipping school he meets Mio a girl 2 years older but is just like him making him want to stand by her side and be there for her, being the support he never had.
However, leaving home and running away together means the medication he used to take daily wears off leading to hallucinations.
