InsomniacEnigma's manga / #animal characteristic(2)

I remember reading this *^* this is so adorable!!! Mc goes to a 'monster' school to meet his childhood friend/love after 10 years of separation

Idol omega x idol alpha + animal characteristics. Mc pretended to be a beta in his resume while he auditioned as an idol. When he got accepted and met the other members, he went into heat since one of the other member was an alpha. The alpha offered the mc if they could be mates, but the mc refused. Despite this incident, he still got accepted to be part of the group. However, this doesn't solve his problem of having an alpha teammate, and this would become a problem in the future.
