Studio MaumC said on April 25 that Part 2 of the series' OST, titled "Sweet & Sour," was released at noon across major music platforms.


"Sweet & Sour" is an upbeat house track that captures how falling in love can make ordinary moments feel both sweeter and sharper. The song is being released in two versions: one performed by Say My Name and the other by 16.


16 wrote the lyrics, composed and arranged the track. Studio MaumC also uploaded a sketch music video of Say My Name’s recording session and a choreography challenge video performed by the group to its official YouTube channel and social media accounts.


The Absolute Value of Romance is a high‑school teen series about Yeoui‑ju (played by Kim Hyang‑gi), a student who wrote BL novels about handsome teachers and then unexpectedly encounters them in real life. New episodes stream on Coupang Play every Friday at 8 p.m.
