Im scare of continue reading it again but does anyone know why the tittle is given?

Mafuyu got asked what kind of word(s) he wanted the band name to include. He then said since yuki's mother gave him the guitar, he wanted the band name to include "gave". Now since the original band name was " the seasons", the guy with the short hair (I forgot his name) tried matching gave + seasons and it turned out as "given". I guess that's why the manga is called "given" since that word represents yuki's guitar and all the memories it holds and also the band's name.
