Bokuto: Hey bro

Kuroo: Yes bro?

Bokuto: I've been thinking for the whole day about this... I still can't find the answer to it

Kuroo: wats that bro?

Bokuto: I've been wondering wats the taste of blood

Kuroo: well taste ur own blood then you'll know

Bokuto: but I don't wanna cut myself or smthing

Kuroo: owh u got a point there... How about licking iron?

Bokuto: why iron?

Kuroo: cause our blood contains haemoglobin which had iron in it so maybe the blood taste like iron but in liquid form

Bokuto: OMG BRO YOU'RE SO SMART

Kuroo: IkR

They ended up licking iron and told this awesome theory they thought of to Kenma and Akaashi

They are not impressed

Out of all the subjects I study, science is my fav xD
