who am i ?

i always wonder who am i ? beside a name for me, beside a son for my mum, partner for my gf, bro for my bros, friend for my friends .... who am i ? i always believe when you treat someone nice, they will treat you nice too, but i guess i was wrong .... when you treat someone nice he/she will only take it for granted and wont know how to appreciate.

誕生日はちょうど別の孤独

私はすでにそれを使用した

自分自身にハッピーバースデー
