Haesung (해성)

The structured facts describe Haesung (해성), a vocalist, MIDI programmer, guitarist, songwriter, and composer who is a member of the group Viral Affair. The narrative material provided, however, concerns BIGBANG's Daesung and contains no information about Haesung. Drawing on invented or misattributed facts would violate sourcing rules, and the available material on Haesung is too thin to support a developed profile.

What can be stated accurately: Haesung, born Im Haesung, is a member of Viral Affair, where his credited roles span vocals, MIDI production, guitar, songwriting, and composing — a multi-hyphenate position within the group. Beyond that, no further sourced detail — debut date, discography, chart performance, or career narrative — is present in the provided material.

A profile built on these facts alone would be a single accurate sentence. Padding it further would require invention, which house style prohibits. If richer sourced material on Haesung becomes available, a full-length profile can be developed at that point.
