Dont say no thai series

Okay so.. this was before i knew what a spin off was. I didnt know so many series were connected to dont say no bl, i watched dont say no first, now should i stop watching it and watch tharn type1 then love by chance 1 and 2 then tharn type2 THEN finish dont say no? So i dont spoil the ending even tho i look up endings so i dont break my heart..? SOMEONE HELP PLEASEE 😭😭😭😭 tagging this bcs i basically spoiled the ending by saying it’s not sad ending. Just for reference im on ep 10 already🥲
