ルール (rūru)

anata no yotei ga ki ni natta mokuyōbi dō shiteru ka na?
kyanseru ni natta mama no hajimete no yakusoku
"aitai" to iu koto ga naze konnani muzukashii no ka na

hito o aisuru no ni atama o tsukau no wa yameyou
nani mo kangaezu ni massugu butsukattemiyou
itsu datte kokoro ni kimeteiru noni

totsuzen furidashita ame ni nure nagara haitta kafe
yokogao ga niteita hito o bon'yari to miteita
"aitai" to tsutaetara donna kao de kotaeru no deshō

hito o aisuru no ni rūru nado nakatta hazu
kizutsuiteyuku tabi kiyō ni hanareru keredo
sore ga otona narabanaranakute ii
hito o aisuru no ni atama o tsukau no wa yameyou
nani mo kangaezu ni massugu butsukattemiyou
itsu datte kokoro ni kimeteiru noni
