Late, but for the sake of anyone else confused it is indeed platinum. The Japanese word for platinum is 白金 (hakkin), spelled with the kanji for "white" and "gold". White gold is a different substance (originally developed as imitation platinum) composed of about 75% gold alloyed with other metals like zinc and nickel. In Japanese it's called ホワイトゴールド.
Watermarks... are you serious?! And why on the scenes even if it's in a corner it's on a drawing... His name is Wataru and please don't rewrite anything.
Especially so if you make the mc sound even more pathetic... on page 3 wataru says "Ah Thank you very much" Not "Oh... I-If that's fine with you, then by all means." He didn't stutter.
On page 4 second text block: If things continue like this, I'm afraid I'll be attacked by fans of Girasol, instead because of the motor boat...
Page 4 second last text bubble: If something were to happen to Wataru-san, we wouldn't be able to take a bath or have your delicious meals anymore.
So many altered sentences... seriously "winner winner chicken dinner!!" Zero respect for the authors work huh...
(The 4 White Gold coins are actually 4 Platin coins, Platin is written in japenese as White Gold but the actual transation for white gold is alot longer.)
Please get your old tl back and be stricter with the tl choice, rewrite is the lowest one can do as scanlator...
