I once read either a manga or a webtoon about a male makeup artist and a female photographer in a partnered competition. I just vividly remember one chapter where a rival destroys all the red products in his kit for a themed photo competition and the rivals also end up stealing their initial idea of tying in red with a first love. The protagonists ended up using a green lipstick and making the photo black and white & inverting the color of the lip. Any help would be appreciated!
