What scandal?
okay so back then what i heard happened was that the artist used to draw sh*tacon and like baby p*rnography (yes literal BABIES) with much older men under a different alias (name) before they starting drawing Dear Benjamin
so when it was found out, the author of the book was like i don't want someone like that to do the art anymore and also the agency so yeah they removed the artist from the work and now replaced them with this new artist years after
Comment from @starflea
I'm too lazy to explain it myself (〜￣△￣)〜
WTF
With the scandal surrounding the previous artist, I'm just grateful that the author is allowing the webtoon to continue. Most of the time, good stories get dropped so yeah ╮(￣▽￣)╭
