i have a prompt for you: alpha jeonghan and omega joshua since you like yoonhong.
jeonghan gets misjudged for an omega by carats. and to disprove it, he fucks joshua on stage at a concert. his huge knot makes the rest of svt to go into heat on stage. so jeonghan fucks them too.
then when joshua is jealous, jeonghan fucks a baby into him and only him. the baby ends up inheriting handsome looks from jeonghan instead of pretty looks from joshua so joshua is sad. jeonghan promises joshua to keep breeding him hehe.
