'' I wish things were different Jungkook ... why did I have to fall in love with him ? Things would be so easy if he was you ... if you were him ... I hate myself for making you suffer like this ... I'm so sorry ... '' before he can get more words out, he feels pressed against the otherboy's chest, breathing into the crook of the maknae's  neck, crying on his shoulder, his strong arms holding him tight.
'' Hyung ... I'll do anything for you. I promise, everything will be okay. I'll protect you. '' He whispered as he gently caress his hairs from his left hand, his other hand around Suga waist, pulling him closer.
Suga’s body shook with every breath in and he gasped in silence , still crying against Jungkook's  chest. Everything felt like too much to him. There was too much pressure and anxiety roaming through his body, tearing him apart from the inside out. All the memories with Yongguk, from their first kiss to the break up ... he tried so hard but nothing was working, he was so tired of feeling this way  ... 

Jungkook slowly ran his right hand through his Suga's back, he then started to rock him back and forth silently whispering comforting words. He could feel his pain, for him to broke down like this in front of someone, Jungkook knew that Suga truly loves Yongguk. This made him sad but for now, the only thing that matters was his hyung. His hyung’s happiness was paramount, and no matter how much it hurt him, how much his heart shattered knowing that he would never love him, Jungkook would still do anything to see him smile again.

Suga went in rehab, there he met Yongguk who he fell in love ... but Jungkook the over-protective maknae is also in love with him ... to the point that he made a deal with Zelo in order to protect Suga and Yongguk's secret.
