Koi to Uso

Koi to Uso has the most similar vibes to White Album 2 that I've watched since then. It's not only the love triangle, but the betrayal that will inevitably come between friends (in this season, and especially if there is a second season). The difference in this anime is that the betrayal is overt and accepted between everyone, which is strange in a way but the concept of the government choosing a partner for you is also different. Potentially White Album 2 without the musical aspect.
