Sometimes we forgot that we should treat him as a baby because internationally he's still 3 years old.....but he grows up so well. This smart big boy doesn't like to be called baby.

Seungjae is the cutest kid ever. I’m in love with him. He did such a good job!❤️❤️❤️

His parents really did a good job on raising up Seungjae

When he was in a ferry, he's nervous like a thunder. Now like an apartment. This child's linguistic skill is something!!

Probably the most wholesome content on KZfaq

I always adore this beautiful family. Parents are so much better and such inspiring and also the little Seungjae is truly a blessing from God.

This kid is amazing.... he’s good at everything and he’s very smart at that age

Already a big boy but still he's so cute Sungjae 😁😍

Seungjae is getting so big it makes me cry!! He did an amazing job love him 💗

OHMYGOD HE'S BECOMING MORE AND MORE HANDSOME EACH DAY 😍😍😍 DON'T KNOW WHAT TO DO WHEN YOU LEAVE TROS PLS DON'T GROW UP FAST BABYYY

This kid is a treasure.. You know seungjae will do well to every challenges he's going to face

I am so in love with this boy... so intelligent, witty, sociable, respectful, etc. etc. His parents must be congratulated for raising such a lovable child. Kudos for a job well done!!! 😍❤️😍

The way he said loudly “Hwaiting” and “Play ball” impressed me extremely. Some athletes often do that to get more strength and confidence. Could believe that 5 year olds boy know that too.

Seungjae sings so much better then me😭

Annyeonghaseyo 😊😊😊 I'm Coree from the Philippines 🇵🇭 I am an avid fan of The Return of Superman. I really love kids and admire the korean way of parenting. I've been watching the show since it's debut. I really adore the triplets Daehan, Minguk and Manse .👶👶👶 Eversince they left the show I felt something was missing. Fortunately the new families were adorable but my favorite and I guess everyone's favorite is Ko Seungjae from Bangbae-dong 😂😂😂 I really love this boy because he has high IQ and EQ. His parents are really doing a great job in raising him. 👍👍👍 He shows great communication skills, he's respectful, honest, shows great empathy and has a pure heart ❤❤❤ We really love Seungjae and he is well loved here also in the Philippines. I've been influencing my friends to watch TROS because of him. We just have a request and I know this will really be a big hit. Can you make Seungjae and Taehyung from BTS meet? I am an ARMY and you can also do research that Taehyung really loves children. We would like to see how well Seungjae and Taehyung will get along ❤❤❤ I'm sure BTS will make time for this adorable child. Please KBS make it happen. Thank you and Godbless.

Good job seungjae 👍👏👏👏👏👏
