Mark and Haechan didn't talk at all during the drive to their home. Haechan was looking out the window while frustrated Mark was focused on driving. The two arrived at Y/N's house first to pick Minjae up. Haechan opened the door and saw Y/N holding a sleeping boy. "Hey Y/N, thanks for watching him!" Said Haechan taking the baby boy into his arms. "Yeah, no worries. Take care! Bye!" Said y/n. Just then, another car appeared and Sungchan walked out to take Somin. Haechan flashed a smile at them before going to the car. Haechan opened the passenger seat and sat and made Minjae sleep in a comfortable position. Haechan admired the younger boy. Mark looked at them and then looked away and saw that they were now in a traffic jam. Just then, it started raining. Haechan looked outside the window and saw some lightning, he knew what was going to happen so, he covered minjae's ears as the thunder struck. Haechan looked at Mark who was now feeling anxious. Mark had been scared of thunderstorms since he was little. Haechan took Mark's hand and stroked it. Haechan held his son before leaning on Mark's shoulder while still holding his hand. Then, there was another thundering sound but a bit louder making Mark jump in shock. "Hey.... Mark... Calm down baby. Calm down. Hey, how about we switch hmm? I will drive." Said Haechan and Mark just nodded. Haechan knew Mark was not in the state to go out and walk back to the passenger seat so, he handed Mark the sleeping child and went to the back seat. Mark gave Minjae to Haechan and mark climbed onto the passenger seat. Haechan handed Mark Minjae and opened the door and walked out. He immediately opened the driver's door and got in so, he wasn't that wet. He buckled up and looked at Mark who was holding Minjae. Haechan tapped his shoulder and mark knew what he wanted. Mark leaned onto haechan's shoulder while still holding Minjae. Haechan stroked Mark's hair. The traffic light turned green so, Haechan started driving. Haechan parked the car in the garage and they both got out with Mark holding Minjae. Haechan opened the door and entered their home. Mark took Minjae to his room and laid him on the bed. He walked to his and haechan's room and looked at Haechan angrily. Mark just snapped at the time. "Lee Donghyuck" said Mark making the younger get goosebumps. He looked at Mark and mark looked at him back angrily. Haechan explained everything to Mark.
After explanation cuz I ain't good at explaining:
"Hyuck... What you did was right but, do you have any idea that what you were doing was illegal. If you told me, I would have taken action against them-" Mark cut himself off when he saw a tear fall from haechan's eye. Mark took the younger into his arms and laid them both down. So now Haechan was on Mark's arm crying. Mark comforted the younger. "I forgive you love, but can you please leave the Red 3?" Said Mark and Haechan nodded eagerly. Suddenly, a knock was heard on the door. Mark walked towards the door and opened it revealing their son. Mark took Minjae and closed the door before laying him down next to Haechan. Minjae dozed to sleep as soon as he laid down so Haechan and mark chuckled at the scene. Mark looked at Haechan before grabbing his chin and kissing him. After the kiss, the family had a cuddle session.

Sungtaro:
After picking Somin up, they went to their home. Somin was watching tv when Sungchan grabbed shotaro's hand. "Explain..." He said. And shotaro explained everything. Sungchan didn't say anything. He just hugged the elder and kissed his forehead. "You being safe is more important than a fucking painting." Said Sungchan before kissing him on the lips. Suddenly, Somin got up from the sofa and shouted. "DADA AND PAPA, WIF YOU KWISS ONE MWORE TWIME, I WILL TWELL GWANDMA!" Sungtaro chuckled before tickling Somin. The family enjoyed a movie session.
