Thank you so much!!
It was a BL manga. I remember one chapter where the main character is so excited about his birthday because his lover is gonna celebrate it with him or sth.. I think they went on a date? But at the end, the lover disappeared because he was dead a long time ago. On his birthday, and he couldn't get over it...
