[Demo 4.5] Implementation of NPC Friendship System and Special Events in

This time, we tried building a new system and creating animation using large illustrations. The animation is still a little rough, but I'll keep trying!
【Update Details】
◆Implemented a system for bathing at the hot spring.
- You can enter the bathhouse after paying the fee.
◆Adjusted so that Miria appears in the bath after the event where you rescue her.
◆Implemented a system where your relationship with NPCs improves when you talk to them in shops or at the bathhouse.
*Currently, only "Miria" in the item shop has this system implemented.
*Other NPCs do not yet have this system.
*In the trial version, favorability can only rise to level 1.
◆When the NPC's standing illustration is displayed, you can determine the favorability level by looking at the four heart marks on the right side of the screen. (The number of red hearts indicates the relationship level.)
- Points gained for each action:
Talking to an NPC → 1 point
Performing a special interaction → 2 points
- 5 points are required to reach relationship level 1.
*Once you talk to an NPC, you cannot gain any more relationship points by talking to them again.
To increase your relationship with an NPC again, please Sleep at the infirmary first.
◆ Special skinship interactions with NPCs will now become possible when affinity level reaches 1.
◆ A special animation has been added for skinship 1.
Fixed a bug that caused the character portrait to appear incorrectly when naked while pregnant.
