Heavy wooden box Japanese Lyrics

♫ Heavy wooden box ♫
(Len's song)

sayōnara akarui mirai e
me no mae ni mieru hako no naka ni boku o tsumete
konnichiwa kurai mirai e
hako ga nanika ni hiki zurare moete kemuri ni natte yuku

haikei sochira no boku e kurushiku nai desu ka?
haikei kochira no boku e waratte nai desu ka?

ano hi boku wa jimen ni sui koma reta ki ga shite
hitori de naki mashita
boku wa nani mo shite ima sen yo
ashita mo boku wa ikite iru hazu deshita

boku no kutsu wa ari mashita ka?
boku no tegami wa mitsukari mashita ka?

boku ga saigo me ni ireta mono wa
tsumetai concrete to sora to kumo deshita
