The "ミ☆(*._.)" emote is a Japanese emoticon that represents a shy or embarrassed expression. It can also be used to convey a feeling of being flustered or overwhelmed. The "If You Say So" emote is typically represented by a person shrugging their shoulders and holding up their hands in a gesture of surrender or resignation. It is often used to indicate agreement with someone else's statement or decision, even if the person using the emote doesn't necessarily agree themselves.
