Now need I remind you guys this is just my theory and how I see what happened based on what I read from raws/This chp. Hopefully things will get resolved in later chps and we actually find out how tf wooyoung found out he was pregnant/what actually happened in the first panel.
Dad took him back to Korea. Cha figured that out, finished all of his important work. Flew his ass to Korea to meet the dad and ask for wooyoungs hand in marriage. Wooyoung found out about cha being back in Korea. Took his ass to the streets with no shoes on and zoomed to cha's house then bam y'all know the rest.
If y'all are confused there was a time skip between the panels of cha being on the phone with Liam and then the scene with secretary.
If y'all are wondering how cha found out. Most likely on his phone call with Liam they had a discussion Liam tells cha about being on the phone earlier with wooyoung and telling him that he was going to call him back and tell him about the person who inquired about him working there. Cha most likely put two and two together that the father took him and that he was back in Korea hence him being calm In later panels. It's not the first time that the dad tried to separate them nor will it be the last. And y'all know the rest he flies to Korea after taking care of his work and was going to propose to wooyoung so that the dad doesn't keep worrying about him/keep thinking that he is playing around with wooyoung. Wooyoung shows up and so on

Now this is just what I came up with when I read the raws with my shit Korean. So hopefully it gets explained properly in the next chapter cause all ik is that in the next chapter the go to the hospital to see about the baby.
Hopefully they also explained how tf he found out about being pregnant. I'm going to assume he bought a test and did that.
