I was curious/baffled enough by this to actually go look at the raws to see if there was any actual reason for this beyond hallucinating garbage AI OCR MTL operated by someone who has no idea wtf they're doing (there wasn't), so here's a quick 1550ese to Japanese/English guide just for giggles
1550: I got excited earlier, did 1550 also develop due to this fact?
Jpn: 私もさっきのエッチでデキちゃったってわけ?
Eng: So that sex we just had got me pregnant too?
1550: Then you're going to need help to get 1550, right?
Jpn: それを手に入れるための力が必要なのよね?
Eng: And to get it, you need to be powerful, right?
1550: I'll try to do 1550.
Jpn: わかったがんばってみるよ
Eng: Got it. I'll try my best!
1550: 1550 is truly incomparable.
Jpn: 間違いなく…♡
Eng: There's no doubt... ♡
tl;dr this guy needs way more fucking help than just a proofreader
1550 mean PREGNANT!
1550 means POWERFUL!
1550 means MY BEST!
1550 is truly INCOMPARABLE!
1550. The new scent by Xistian Dior.
See? it's obviously a perfume add. That way, making no sense is by design!
