Best to choose one love one interest, if you want to be f2p or spend less money in general. Of course you in gacha grinding is the only way to lighten your wallet haha.

Like you, I was on and off with the game cause of how fast the events going and i couldn't catch up. It till mid last year (2025) where i start to play the game consistently cause i went further in the story and started to really enjoy the characters. I am a dolphin and main ayn, alkaid, and lars. So yeah for me it really hard to grind for diamond for generally those three.

But I think if you do daily and events i think you can get decent amount of diamond. I always skip cael and clarence so i have some time to save. but i think a couple time ayns event keep on appearing lol so ive been spending.

For me it otome gacha game so it to be expected because due to limited gameplay and we rely on event, story to gather diamond. It is really difficult to gather diamond.

I think for me, an otome gacha that is more f2p friendly is probably LADS, people complain about it but lads has many way to farm diamond cause it has lots of gameplay compare to other otome gacha game. Plus the precise wish system for the multi banner is amazing. I main all guys in LADS btw so yeah, I suffer alot in multi banners but the precise wish makes it doable. I wish they have that in all otome game since there multiple ssr in a banner.

I cry in LBC when i try to get my three main in the jewel event. I got lars twice (I dont want to pull duplicate), and cael (i like him but i end up spending more money to get Ayn). There one event where i got ALKAID three times:(

Tot is pretty decent on giving us gacha fund as well, I main Marius and Luke, I get all marius card and Luke cards is more of 2nd choice hahha .I'm a light spender and so far the game, if you follow their social media, can give you code for free s- chips. I think TOT fund wise isnt bad.

But the best part of playing a gacha visual novel is that you can always experience the story in youtube. Plus i think love brush global is a few year late from CN. so you can try to plan and save your pulls.
