mayb wooju's parents are overly sympathetic towards jiheon bc of his family situation (assuming they know how his mom treats him, mayb they're trying to compensate some parenting he needs? idk) and trust him to an extent regarding wooju (like, he wouldn't harm wooju out of malice).
it's still weird ik but i hope they're just not showing their emotions fully bc they're being mindful rather than not thinking of it as a big deal

wooju's dad is prob assuming that jiheon was pheromone bombing wooju to make him present as an omega, right? bc it makes no damn sense for him to be so "meh whatever" abt it (•ㅂ•)
