Bump for translation checking! It would be only one bubble, the orange one in the last panel. I could not tell apart the kanji. It might be some thing dirty like a love drug or something, because of the punch line.

Also, in the yellow bubble of 3rd panel, I wonder if it was the author's intention to make her stress the word "iku." It sounds like "Let's come together;" knowing she's usually the troll of this comic.

Oh so it was 秘薬 I always thought it to be 秋葉 lol
The artist's handwriting became so sloppy when he finished this comic.
