Allow me to explain another thing to this AU:

Instead of Choi Jung Soo receiving the deal from GoD when he was almost 21 years old, Choi Min Yong was offered first when she was almost 31 years old.

The offer was the same as in the TCF world and of course Min Yong chose to save Sirin and the rest, dying with Baek Min Jun.

Baek Min Jun reincarnated into Sui Towel instead of Lee Soo Hyuk in TCF (In the future I will do a REACT on this).

Lee Soo Hyuk, Choi Jung Soo and Kim Rok Soo died while leading the way to protect other groups.

Rather, Choi Jung Soo received an deal from God of Death as suggestion:

1] Choi Jung Soo died together with Lee Soo Hyuk and Kim Rok Soo.

2] Choi Jung Soo will live and transmigtion into another world.

Jung Soo doesn't want to die nor does he want to leave his Hyung and Dongsaeng.

And he chose the first one.

(Both Rok Soo is 36 years old and Jung Soo is 37 years old and I don't know about Lee Soo Hyuk real age)

The three reincarnated into [The Birth Of A Hero], a side story about Cale Henituse having three children.

OG!Cale Henituse got pregnant at 14 and a half years old (I'm not P*doph1le at all. If you want to know more, just read on). She became pregnant thanks to the Cube of Life (This part will appear) beamed in that she accidentally found inside a strange dark cave.

At that time, Cale went with Wanda, Naeus, Marcus, Natasha and Lucas to explore inside the strange cave (She had already asked Count Deruth to let her out), so she went deep inside and found a cube projecting into the cave. causing her to faint on the spot.

OG!Cale's team found her unconscious on the spot and immediately brought her to their home. When Cale woke up, what Cale saw were their shocked and worried faces, which confused her. When Natasha said that she was pregnant because the light from that strange cube shined into her like that.

Knowing this, Cale was a little surprised inside even though she kept her expressionless face on the outside. Instead of being worried like many others, she felt a little happy for some reason but Cale wanted to lifes inside her was born safety.

To avoid trouble, she asked Wanda to put magic in her fetus to avoid detection. Of course, Cale also asked Natasha to make safe pregnancy medicine for her so that Ron, Cale's personal butler, would not be suspected.

That's when Cale gave birth to three children on her 15th birthday. It was also when she let her puppet stay living in the Henituse Terrority while she took care of the children and Cale's group helped her with that.

That means Lee Soo Hyuk, Choi Jung Soo and Kim Rok Soo reincarnated as Cale Henituse's children:

The first child, Lee Soo Hyuk's name is Cyrus: meaning "The Sun" or "Throne"

The second child, Choi Jung Soo, is named Casimir: it has the alternate meaning of Miru in Korean which is "Dragon", in Europa it is "Peach" or "World".

The youngest child, Kim Rok Soo, is named Ciel: meaning "Sky" or "Heaven".

Also, in the second life of OG!Cale, Kim Mio, there was a successor named Kim Yuna (or rather, she wanted to be accepted so Sirin accepted), the second Sirin took over her when she was still young. 16 years old, 2 years younger than Rok Soo.

Kim Sirin in her 3rd life has 4 Abilities:
• Copy: ° Record
°Instant
°Embrace
°Slash
• Nullification
• Psychokinesis
• Gifts

When Yuna was 37 years old, Mio was 49 years old, the day Sirin decided to sacrifice herself for Kim Yuna and other groups. Kim Mio took her own two Abilities [Copy], [Slash] and [Nullification] and used [Gift] to give them to Kim Yuna, believing that she would take care of the rest for her. Even though Kim Mio didn't want her disciple take her's burden, Kim Mio has no other choice.

Although Kim Yuna was heartbroken by the death of her teacher, because of her wish, Yuna quickly overcame it and led everyone.

SPOILER:
Choi Min Yong went to find Kim Yuna and told her that Kim Sirin was a Reincarnator, Transmigtor and Regressor, surprising Kim Yuna because not only did she see Kim Sirin's partner but she also knew the truth of the life of her teacher.

Choi Min Yong also said that Sirin's mother, that is, Cale in her First Life, was reincarnated into this little girl on Earth.

Also saying that her family was attacked by monsters caused a heavy traumatic impact. Kim Yuna of course knew what Choi Min Yong wanted to say next, and Kim Yuna decided to adopt her as her niece.

---------------------------------------------------------

As everyone can see. I want OG!Cale to be happier, I'm quiet bit unfair for OG!Cale because KRS!Cale gets pain mixed with happiness while OG!Cale is full of pain in his old world even though he is happy right away when he met his mother again on Earth 1.

So I made this because I love OG!Cale and also love Kim Rok Soo so I will make them both live in happiness.
(NOTE: I'm not make OG!Cale stolen TCF!Cale's happiness, I just want both of them deserves the love and joy in their life)

In React, there will be parts in this that are similar to TCF but also different because I added OCs as well as changed the plot a bit because I combined TBOAH/TCF x HI3rd.

I makes OG!Cale little OP but there will be limits.

You guys don't need to worry about Reincarnated!Jour because Kim Yuna already takes care of it.

Also, OG!Cale's personality will be like similar to TCF!Cale with the personality of a mother taking care of her child and the personality of HI3rd's Sirin with a little bit of Elysia.

Cale is Primordial Herrscher in this. Little parts of her Powers and Skills are sealed by Stigmata Seal so only uses half of it.

Furthermore, I like Tensura and HI3rd so I will make OG!Cale's power exactly the same as Primordial Herrscher in {World's Ego} in Wattpad.
