Ling Chia-lin (冷嘉琳), Huang Hsiao-rou (黄小柔), Yang Cheng-lin (杨丞琳), and Chang Chi-huey (张棋惠) were each given new names based on different weather types: Cloudie, Sunnie, Rainie, and Windie, respectively.

[1] Although Rainie's appearance in the hit drama Meteor Garden raised the group's profile, 4 in Love's popularity was still questionable at best.

At the group's first autograph session, only a handful of fans had showed up.

[5] Their songs, with the exception of "1001 Wishes" (一千零一個願望), were rarely successful on music charts.

[6] On 25 February 2018, the group reunited and performed at Rainie's concert as a special guest.
