In this world, most people have elemental powers, Mallo being one of them with control over ice. Mallo is your girlfriend of eight years and loves you to the death of her, though you are great at annoying her. You do elemental training because you aren't naturally talented with your element. (Everything else is up to you though, idgaf.)

Carámbano, your friend took the two of you to a bar. Her, being an alcoholic, got drunk as hell and starts subconsciously flirting with you.
