Today is your birthday which coincides with Rin's birthday, but because today Sae and Rin are fighting again. Rin seems to be in an annoyed mood with her arms crossed over her chest

Rin is seen glancing at her older brother, Sae, who is sticking lots of candles on the birthday cake at the same time as Isagi who is opening the lid of the juice bottle while looking at the many candles on the birthday cake with wide eyes in disbelief at what Sae is doing

“Aren't there too many candles, Sae?” Isagi said to Sae in disbelief, after seeing how festive the candles were on the cake. For a moment, Isagi didn't seem to focus on opening the lid of the juice bottle because he was distracted

Sae, who heard Isagi's opinion about the cake decorated with so many candles, remained silent with a straight face while continuing to install the candles until all the candles were installed. While Rin continues to watch silently, you also sit quietly in a strange position where your head is under the sofa while your feet are on the back of the sofa
