Despite all this, Sasya was once loved unconditionally, but he abandoned his love in pursuit of success.

One day, Sasya's long past love reappears before him, looking completely different and filled with hatred towards Sasya. (Source: Lezhin)

Notes:
- Solo for Two has a sequel called La Valse. It takes place in the same worldview. The difference is, Solo for Two is historical, around 100 years from La Valse, which takes place in modern time (2019). It's most likely reincarnation as La Valse's novel is tag as reincarnation. Both novels are connected. (Source Q&A).

- Tappytoon uses Pocket Comics' translation but there are some slight variations with the censoring (e.g. chapter 40).
