Mikazuki's still ayaka's only #1 single to date so in a way or 2 , the public still have a strong long lasting impression on the song
BREAKERZ's SUMMER PARTY is also quite romantic in a way or 2 hehe . I love the somewhat
CHEESY lyrics that DAIGO wrote in there

even though the story behind it's really sad .__.
The guys's Winter Bell is also awesome too . It's 1 of those songs that lyrically will make you go awwwww
DAIGO has the ability to write songs that're either random , weird , cheesy , serious & when he write serious ones like Hikari , it's a home run for the group lol
