The song talks about an unnamed person's undying love for their crush, sending him/her love letters every day for 15 years, never recieving a reply.?

In the first year, the person says they were reckless, sending letters every day without fail.

In the second year, the person was still reckless, their house catching fire and they didn't notice until only their shirt collar was left.

In the third year, the person calmed down and published the letters on their mixi journal, and their MyMixis maxed out the counter.

In the fourth year, the person wrote for a magazine and released a poem compilation. They quit their job as an office worker.

In the fifth year, the person was a pro poet, and women from 20-34 read his/her works. He/She called them "inexperianced pansies".

In the sixth year, the ? person was in a horrible accident. All of their bones were broken, and all their organs damaged, yet they still wrote their letters to their special person.

In the seventh and eighth years, the person spent their days comparing their crush to things.

In the ninth year, the person suffered a blow to the head and lost their memory, but not their love.

In the tenth and eleventh years, the person's memory hadn't returned, and all he/she wanted was a reply.

In the twelveth and thirteenth years, the person's memory still hadn't returned. He/She still loved the person. That was all he/she had.

In the fourteenth year, the person's memory still didn't return. Every day was frightening and uneasy. All the person wanted was to talk to their crush or look at him/her.

In the fifteenth year, their memories returned. The person collapsed into tears, because they remembered that their crush had died 15 years before.

After 16 years, the person is still writing, knowing that they will never get a reply, but the person still loves their crush, even though they can't seem him/her anymore.
