As you can see in the above's notice, this manhwa already has 48 chapters. Any one want spoiler? Here:
The kidnapper's car crashed and flipped over. ML rushed to it and managed to bring the kid out but the car caught fire and exploded. They didn't have enough time to move away so ML covered the kid with his body. Then he stood up and brought the unscathed and sleeping child to the MC. MC asked why he did it and ML answered because the kid is precious to the MC and to him (ML). ML also praised MC for raising the kid and he said he already knew it was their child and that he was sorry for not knowing earlier. Then he collapsed (had massive glass and debris stucked in his back).
MC and his son went to visit the ML in the hospital. ML was in a coma. Then ML's mother came. She and MC had a conversation outside the room while the kid is inside. The mother said the culprit was her daughter and apologized. She said they were already looking for the daughter (she fled and left her own child, apparently). MC told the mother that he's willing to let go of the ML but he will never give up his son. The mother actually agreed (lol. she's nice, guys) but she still asked the MC to talk things with ML when he wakes up. She said she wanted them to be happy together.
