A catchphrase that later evolved into a meme that was originally said by Makoto during the Maho Maho Kingdom in-game Princess Connect! Re:Dive event, expressing regret for falling in love with Yuuki, despite her best friend Yui also being in love with the same person.
Use this tag if any Princess Connect! characters expresses guilt or regret towards Yui for taking away Yuuki (the usual suspects are the aforementioned Makoto, Kasumi, Hiyori, and Rei), if Yui is visibly upset or jealous of Yuuki doing something with someone else, or if the phrase itself appeared in the image in any form (usually by swapping Yui with other characters).
