I remember a scene from a manga/an anime where a character (that I believe wasn't part of the main cast) kept on calling their deceased lover's phone to reach the answerphone and hear the voice of their lover aka them saying "I'm not available, please call me later"
If you know what it is, please tell me ┗( T﹏T )┛
The words he put on his walls broke my heart
i know. the fact that the room is filled with them makes it more depressing.
