The Cooliest's manga / #Alpha × Omega(86)

Everyone thinks this guy is an Alpha, including this Alpha childhood friend that he's been in love with for a long time. They've disconnected for a while but are to be reunited again after his little brother is in a relationship with childhood friend's little brother and are hanging out in the US.

An Omega looks for one night stands because they have an erratic heat cycle because he used to have a mate but after the nate disappeared, they cut off the mark on his nape. Hence, causing the erratic heat cycle. While he was trying to get away from sus people in an alley, an Alpha who can't detect pheromones saves him and they end up having sex. Gino might be my fave lol
