Need help trying to identify these 2 Japanese songs I heard in a thrift store :(

Heyyo everyone, my first post here~

I’m trying to find the names of these two songs I heard while I was in a Japanese thrift store in Malaysia.

I came across these songs while I was thrift shopping and they were reallyy catchy to me hehe
I tried using Shazam, Google music finder and AHA Music but none of them could identify the songs 🙁
So, I figured Reddit would be my last resort..

I managed to record a video of the songs playing in the store. Tbh, I’m not sure if they’re actually two separate songs or just one song..hopefully someone here can help me identify them

I hv uploaded the video to YouTube since I can’t upload it here:
Song 1
Song 2

Thanks in advance! 😀
