You can play the game however you want. Adriel, Barghest, Jason, and Grigori are the four love interests. The story is written as a single route so it honestly doesn't matter who you choose and there's an option to skip romance altogether if that's not your cup of tea, because it's a story about friendship as well. ♥ And if it makes you uncomfortable I won't be offended. Different people enjoy different things. ^^
