Spoiler??

there is 2 brothers we haven't met https://twitter.com/hhsis2/status/1219128864003092481/photo/1

Beautiful family *-*

2 brothers and it looks like 2 who are just new in general (one has these bright ass blue eyes. I THINK the other 2 are related to Taehan I'm not sure

So 4 new characters

Those characters are from another series Aeju is working on that I believe is totally separate from Love Shuttle. She’s going to be working on 2 series at the same time. The one on the left especially looks like he could be related to Taehan so I can see why you might have thought that, lol.

Oh! My bad! Lol

I saw the family pic and then that one..and in the one with the 4 dudes, one looks like Taehan, and another like one of doyuns brothers from the family pic

they're all doyun's brothers including doyun himself in the fourth picture as the youngesy. aeju is showing the order of brothers from the oldest to the youngest.

There are two different tweets from Aeju that are teasers with new characters. The first one is the one with Doyun’s family ( https://twitter.com/hhsis2/status/1219128864003092481?s=21) and the second one is the one for the new series that I was talking about ( https://twitter.com/hhsis2/status/1224646263280291840?s=21)

People seem to be confusing the two a lot.

ooh okayy. sorry for the confusion
