What's a ML you think is bland but everyone loves?

For me it's Itusomi from A Sign of Affection, everyone hypes him up but when I read it he was just so boring. Don't get me wrong he's nice, but he's bland imo. Also, Sungyeon from Hosik's story; I LOOVE that manhwa but it felt like he was just there. He's super nice, but if you asked me what his personality is like, I couldn't tell you.
