You see, I sympathize with Dojun and I understand where he's coming from, but it doesn't really mean he was right in this situation. Dojun's past with Dohwa and his insecurities explain a lot of his actions right now (especially with how he treats Doyun) but that doesn't make it right.
Yes, it's normal to be protective over your siblings, but the way Dojun treats Doyun is very toxic. We as the readers understand why Dojun does this, but having an explanation doesn't mean it's justified. Look at how Dojun has spoken to Doyun and treated Doyun in the past. He may have good intentions, but he is taking his overprotectiveness of Doyun way too far. I know Dojun cares about Doyun, but it's gotten to the point he infantilizes Doyun and doesn't want him to make any decisions as an adult/have any privacy.
Remember when Dojun and his mom discovered Doyun was sleeping with Taehan and how Dojun demanded Doyun moved back immediately? Doyun internally mentions that it took him years to convince his family to let him move out and live his life.
Doyun can be immature, however, it's still clear that he's an adult. His immaturity is more in the field of romance/his very late puberty but he is obviously an adult. I don't blame him for lashing out at Dojun considering how Dojun treats him (again, it doesn't make it right, but I genuinely cannot blame him). Doyun has made it pretty clear he wants to make his own decisions and had every right to stand up for himself imo (especially because Dojun didn't even try to get to know Taehan and just shot him down immediately) but he took it too far.
The Doctor should honestly just fuck off lmao why is he even here like,,,
I honestly think everyone sucks in this situation (except Taehan my poor mans just tryna live his life). Dojun can't keep treating Doyun like this and Doyun should've calmed down a little with digging into his brother's insecurities.

Yohan is in the Yohallway touching Soohwa with his Yohands because he is feeling Yohorny. It's getting Yoheated in the Yohallway. He's quite Yohard for Soohwa so he Yohalted the cafe's business so he could use his Yohan to make Soohwa Yohorny so they could do the Yofricketyfrack.
Thank you for coming to my Ted Talk
I have a headcanon that the reason Hyeon-Oh emphasizes Seung-Hyeon’s chest is because his chest/clavicle is canonically Chaejun’s favorite part of his body
