Renowned gynaecologist Dr. Veronica Yu, believed to be a victim, and a young man named Joe Lee, seen near the syndicate's lair, are questioned by detectives Sit and Wong, leading them to share their stories.

His employer, Mr. White, introduces him to the internet fraud syndicate that scams people through dating apps by initiating online relationships.

As they start chatting, Mr. White and Joan grow suspicious of Yu, noticing her luxurious lifestyle and lack of social media presence.

Upon returning, Yu sees a photo of Lee arriving at Hong Kong International Airport on Facebook, mistakenly reposted by a new recruit from the real Jeunet's account.

Lee borrows a power bank on the street and calls Yu, but his account is remotely logged off by the scammers after he greets her in Cantonese.

[5][8] After being enlisted, Ho approached her mentor Chan Hing Ka to join the project as producer, and the two revised the screenplay to focus more on the romance and emotional aspects rather than the crime elements and warnings about scams.

[5] Ho also insisted on filming the latter part of the movie overseas, believing that people would be more emotional when far from home, and chose Hokkaido as the backdrop for its leisurely and relaxed atmosphere.

[5] Due to a limited budget, Chan reached out to various costume and art designers he knew to join the production team for reduced pay or even for free.

[9] Ng declined a fixed paycheck, opting to work for free instead, agreeing to receive a bonus only if the box office was successful.

[12] Cheung was recommended by Ng, who was impressed by his stage charisma after attending his concert,[8][13] while Tang's role was described as a cameo, as she only participated in the shoot for four days.

[15] A behind-the-scenes compilation was released on 19 August, revealing cameo appearances by Emotion Cheung, Joman Chiang and Ronald Cheng.

[17][18] Location shooting occurred on 16 June at an industrial building in Fo Tan, Shatin District, where Sandra Ng, MC Cheung Tin-fu, Stephy Tang, and contestants from a talent show hosted by the YouTube channel Running Team were spotted on set.

[22][23] On 6 July, Cheung opened a Threads account and mentioned that he was filming in Sapporo in his first post, shortly after the social media platform was launched.

[26] Love Lies's theme song "Penpal" was performed by MC Cheung Tin-fu and composed by Day Tai, with lyrics co-written by Pakkin Leung and director Ho Miu Ki.

[41] Edmund Lee of South China Morning Post gave Love Lies 3/5 stars, describing it as an admirable yet mannered film that, while presenting a thought-provoking premise about romance, deception, and loneliness, ultimately fails to fully explore its deeper emotional themes due to an overreliance on light comedy.

[42] Keith Ho, writing for HK01, lauded the film as an engaging exploration of love and loneliness, highlighting its interesting story, lovable characters, and impressive performances especially by Sandra Ng, while noting the film's unique storytelling method and effective use of Sapporo as a backdrop, though he felt the two detective characters could have been better utilized to provoke deeper reflections on the meaning of love and marriage.
