  "abstract": "In paper arXiv:2002.12065, the author developed a new method to compute the exact overlap formula between integrable boundary states and on-shell Bethe states in integrable spin chains. This method utilizes the coordinate Bethe ansatz representation of wave functions and singularity property of the off-shell overlaps. In this paper, we use this new method to derive the formula for overlap between the Lieb-Liniger Bethe states and the Bose-Einstein condensate (BEC) state. Our formula coincides with earlier result.",
