The seme and uke are cousins. And i think the seme is a model and is still going to uni. and the uke is in the same university. The seme is very "clingy" to the uke which makes his fans in uni very jealous. The girls will then tell the uke to not hog the seme all by himself and to let them sit with the seme during lunch. Which the uke agrees.

The uke keeps holding back his love because of the seme's parents. Because when the uke's parents died, they took care of him like their own. There's also the part when the seme tells the uke that his parents already approve of the seme being in love the uke.

Is it Ore no Mono ni Narinasai?

That's the one! Thanks for the help! 🙂 🙂
