Shinpi he himself said that it's 1 song that they always never fail to perform live (among other staple songs like NO SEX NO LIFE , Ao no Mirai , REAL LOVE COUGH COUGH COUGH COUGH) & it means a lot to the group as SUMMER PARTY / LAST EMOTION's the 1st release of the guys that cracked the top 10 for the trio & since then , every single release of theirs have been top 10 status material
I know the story behind SUMMER PARTY & you're going to go !!! after I told you this
When asked about the story behind this song in various variety shows such as in Shin Domoto Kyoudai which DAIGO appeared in , DAIGO shares that he once courted this girl who had to study as an exchange student in London.
The girl apparently told DAIGO that it would be nice if he came (perhaps not really meaning it). DAIGO took it seriously and went there. While on the plane he was so excited that the lyrics, “Afuredashisouna kono MY HEART” came to mind.
Upon arriving, however, the girl had this “He seriously came,” expression on her face. DAIGO stayed in London for a week, and eventually said the words, “Please go out with me,” but was rejected. (CURSE THAT GIRL WHO REJECTED HIM GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
)
The worst thing's that he dubbed that experience as 'miserable london' ;__; & when he returned back home to Tokyo , he wrote lyrics naturally
lyrics/phrases like 'despair attacks me'
I'm not sure what's the after effects of that song after SUMMER PARTY but I suspect it's LAST EMOTION even though he didn't said whether was a song inspired by the after effects of him getting dumped in London T-T
